1 00:00:03,778 --> 00:00:05,437 Basically what we're doing now 2 00:00:05,524 --> 00:00:07,825 is driver orientation. 3 00:00:08,183 --> 00:00:11,203 Here it's in Giv'at Ze'ev, and in China, I imagine, it will be somewhere else. 4 00:00:11,488 --> 00:00:13,639 So what we're going to do now 5 00:00:13,822 --> 00:00:19,467 is to run a simulation on illegal vehicle commands. 6 00:00:20,167 --> 00:00:23,573 There are a few reasons to do this. 7 00:00:23,600 --> 00:00:29,614 The main goal is to get the driver acquainted with what the vehicle can do. 8 00:00:30,231 --> 00:00:34,405 These are situations that rarely happen today. 9 00:00:34,842 --> 00:00:40,167 But it is important for drivers to know them, get a feel for them, and know how to handle them. 10 00:00:40,804 --> 00:00:44,970 These things used to happen more often, when the steering wheel was sharply turned, 11 00:00:45,527 --> 00:00:47,527 or during unwanted braking. 12 00:00:47,596 --> 00:00:49,596 It almost doesn't happen today. 13 00:00:49,699 --> 00:00:52,802 Still, it's very important to know these things, 14 00:00:53,233 --> 00:00:56,685 to learn these things, and most importantly, to know how to handle them. 15 00:00:56,812 --> 00:01:02,507 Among other things, I am able to see your response time. 16 00:01:03,007 --> 00:01:09,401 We have a pass criteria for response time of one half-second. 17 00:01:09,708 --> 00:01:13,833 Anything over that means we need to improve, anything under that is great. 18 00:01:14,165 --> 00:01:17,395 One more thing I can see here is consistency. 19 00:01:18,125 --> 00:01:23,151 If you respond once within 0.8 seconds, and it takes you 0.3 seconds the next time, 20 00:01:23,199 --> 00:01:25,802 that probably means you’re a bit off focus, 21 00:01:25,842 --> 00:01:33,307 and that can only help us understand how focused we need to be, 22 00:01:33,760 --> 00:01:38,355 and how we maintain that focus as we drive. 23 00:01:38,712 --> 00:01:40,701 I'm running the policy version. 24 00:01:40,765 --> 00:01:42,765 The version isn't what important per se, 25 00:01:42,843 --> 00:01:46,852 what's important is the testing profile we're using. 26 00:01:47,352 --> 00:01:49,634 So I'm running the policy at the moment. 27 00:01:51,936 --> 00:01:53,243 I turn on the display. 28 00:01:55,633 --> 00:01:58,367 It takes some time to run in this setup. 29 00:01:59,385 --> 00:02:03,382 I choose our trip, which is the Givat Ze'ev Test Track. 30 00:02:06,707 --> 00:02:07,493 This one. 31 00:02:08,551 --> 00:02:09,793 I tap "go". 32 00:02:10,468 --> 00:02:15,904 We don't have a localization right now, we'll need to drive a bit to get one. 33 00:02:17,941 --> 00:02:21,130 While that's going on, I'll open the testing profile... 34 00:02:21,300 --> 00:02:26,100 What I select in the "testing profile" is "Target Machine: PC". 35 00:02:27,102 --> 00:02:30,733 For "select profile", I choose "training". 36 00:02:30,951 --> 00:02:33,306 I have all kinds of other options that we don't really care about. 37 00:02:34,020 --> 00:02:38,200 And here, I can basically control three parameters. 38 00:02:38,406 --> 00:02:42,004 The first parameter is speed, at km/h, not meters per second. 39 00:02:42,414 --> 00:02:45,867 The second parameter is the pedal, gas or brakes. 40 00:02:46,144 --> 00:02:50,908 If I open this drop-down I can see that I can send a braking command, 41 00:02:51,358 --> 00:02:56,661 or gas, these are the commands we have, braking and accelerating. 42 00:02:57,178 --> 00:03:04,003 In steering, I have "right", "left", "off", and "freeze". 43 00:03:04,096 --> 00:03:09,336 "Freeze" is when the steering wheel gets locked in the same situation it was in before... 44 00:03:09,759 --> 00:03:12,113 "Off" means that the steering wheel doesn't work at all. 45 00:03:12,444 --> 00:03:16,690 So I'm giving it the maximum value, up until the limiter. 46 00:03:17,246 --> 00:03:19,700 We have limiters, which is basically the "peak_on"... 47 00:03:19,878 --> 00:03:22,836 It limits the speed, sharpness, 48 00:03:23,087 --> 00:03:26,209 and steering wheel speed at any speed we could be driving at. 49 00:03:26,314 --> 00:03:31,733 So you can feel that at lower speeds, 50 00:03:31,870 --> 00:03:35,428 the steering wheel will turn much more sharply than it would at higher speeds. 51 00:03:35,759 --> 00:03:41,233 Since at 20 km/h, we'd probably turn the steering wheel all the way. 52 00:03:41,258 --> 00:03:42,573 That doesn't happen at 100 km/h. 53 00:03:42,705 --> 00:03:45,655 So these are the peak_on limits, these are our limiters, 54 00:03:47,110 --> 00:03:50,602 Both the gas and the brakes are affected by our limiters. 55 00:03:51,118 --> 00:03:56,827 For our first test drive, since this is your first time trying out autonomous driving, 56 00:03:56,866 --> 00:03:58,866 I’ll teach you how to enable autonomous driving. 57 00:03:59,207 --> 00:04:03,731 We'll do a round-trip, traveling at first at 30 km/h. 58 00:04:06,231 --> 00:04:07,467 Just to get a feel for it. 59 00:04:09,015 --> 00:04:11,898 After that, we'll speed it up a bit, driving without any surprises 60 00:04:12,004 --> 00:04:14,004 and without injecting any commands. 61 00:04:15,893 --> 00:04:18,737 We'll speed it up to about 60 km/h, so that you can feel comfortable with it, 62 00:04:19,200 --> 00:04:21,649 and that's when it starts getting interesting. OK? 63 00:04:21,847 --> 00:04:25,400 So here's what we'll do now. We'll put the car in gear, in "drive"... 64 00:04:26,199 --> 00:04:27,456 Release the handbrake, 65 00:04:27,879 --> 00:04:30,458 both hands on the steering wheel... and we start driving, 66 00:04:30,842 --> 00:04:32,842 until we get a localization. 67 00:04:33,967 --> 00:04:37,167 We're supposed to get a localization at the sign. 68 00:04:40,667 --> 00:04:41,522 Great. 69 00:04:41,840 --> 00:04:45,133 Our "on" button for autonomous mode is this one. 70 00:04:45,358 --> 00:04:45,675 "On". 71 00:04:46,152 --> 00:04:46,628 OK? 72 00:04:47,012 --> 00:04:51,233 It's very important that we release the brakes entirely, before pressing it. 73 00:04:51,662 --> 00:04:54,633 I believe that we'll have cases when you will press the button, and it won't work, 74 00:04:54,731 --> 00:04:56,583 That usually happens because your leg is slighty pressing the brakes, 75 00:04:56,583 --> 00:04:59,229 or if there's resistance on the steering wheel coming from your hands. 76 00:04:59,546 --> 00:05:04,969 There are another two buttons on the steering wheel that we use regularly when driving. 77 00:05:05,247 --> 00:05:09,184 This button, just below the "on" button, 78 00:05:09,488 --> 00:05:13,946 is a button that forces the system to identify the vehicle in front of us as an obstacle, 79 00:05:14,012 --> 00:05:16,701 and then, we pass it, if possible. 80 00:05:17,147 --> 00:05:20,867 and when driving at a speed of over 20 or 30 km/h, 81 00:05:21,184 --> 00:05:24,398 this button causes the car to switch lanes, overriding the default setting. 82 00:05:25,959 --> 00:05:31,541 This causes the "policy" to say that the lane you’re driving in now isn't good, 83 00:05:32,150 --> 00:05:35,275 switch lanes. It could be to the lane on the right or left, 84 00:05:35,275 --> 00:05:37,630 based on the traffic, assuming that we're driving in the middle lane. 85 00:05:37,749 --> 00:05:39,958 Does the system decide on its own whether to pass on the left or right? 86 00:05:40,050 --> 00:05:42,325 Yes. In other words, if you're driving in the middle lane, and activate it... 87 00:05:42,325 --> 00:05:46,967 Still driving at a low speed of about 20 km/h. 88 00:05:47,495 --> 00:05:52,333 At over 20 km/h it switches lanes, and under 20 km/h it indicates an obstacle. 89 00:05:52,333 --> 00:05:55,900 - Got it. - The button underneath is less relevant today... 90 00:05:55,900 --> 00:06:01,710 It switches between two modes. One mode is "comfort mode", the other is "sports mode". 91 00:06:02,159 --> 00:06:06,167 The differences between them are our speed profiles. 92 00:06:06,419 --> 00:06:10,967 If we allow the vehicle to surpass the speed limit by 10%... 93 00:06:11,405 --> 00:06:16,889 and there's one more change regarding lane switching... 94 00:06:17,167 --> 00:06:21,558 It slightly increases or decreases our driving margin, 95 00:06:21,717 --> 00:06:25,897 or how close we let ourselves get when we switch lanes. 96 00:06:26,440 --> 00:06:31,236 -In comfort mode, I imagine it maintains longer distances. - In comfort mode... exactly. 97 00:06:31,606 --> 00:06:35,400 "Comfort mode" is very suitable for Europe. 98 00:06:35,971 --> 00:06:39,067 "Sport mode" is better for Israel, because you need to drive more aggressively here, 99 00:06:39,162 --> 00:06:43,267 you need to maintain a shorter trailing distance. 100 00:06:43,938 --> 00:06:47,787 Before beginning the stage when I start injecting commands, 101 00:06:47,959 --> 00:06:52,733 I'll tell you how I expect to take over them. 102 00:06:52,902 --> 00:06:55,653 Largely speaking, once I enable autonomous driving, 103 00:06:55,970 --> 00:06:57,970 touching the steering wheel, gas, or brakes 104 00:06:58,510 --> 00:07:00,510 immediately restores manual control. 105 00:07:00,900 --> 00:07:01,396 OK? 106 00:07:01,978 --> 00:07:02,507 Ready? - Ready. 107 00:07:03,407 --> 00:07:05,407 Your hands always follow the steering wheel. 108 00:07:05,775 --> 00:07:08,300 You can release the brakes and press the "on" button. 109 00:07:10,140 --> 00:07:14,002 Now the car is driving autonomously, it will be limited to 30 km/h, 110 00:07:14,227 --> 00:07:16,227 because I set that limit. 111 00:07:18,850 --> 00:07:21,500 Here's something important. Regarding your right foot, 112 00:07:21,575 --> 00:07:27,964 it's never static. It always adapts to the situation. 113 00:07:31,719 --> 00:07:36,019 If you see that something is about to happen, keep your foot on the brakes. 114 00:07:36,119 --> 00:07:40,167 If someone is tailgating you, and you're in heavy traffic, 115 00:07:40,467 --> 00:07:42,704 meaning that we could end up slamming on the brakes 116 00:07:42,876 --> 00:07:45,767 when we really shouldn't, the right foot should be on the gas pedal. 117 00:07:45,767 --> 00:07:48,733 All of this is meant to shorten our reaction times. 118 00:07:48,733 --> 00:07:54,500 To shorten our braking time. The response time will be identical, 119 00:07:54,500 --> 00:08:02,567 but the time that will pass between the moment you decide until the moment you act 120 00:08:02,567 --> 00:08:04,567 could be shortened this way. 121 00:08:04,870 --> 00:08:07,635 I'm increasing the speed a bit, to 35 km/h. 122 00:08:15,833 --> 00:08:17,833 Increasing to 40 km/h. 123 00:08:19,233 --> 00:08:22,333 Now, just to demonstrate, tap the brake pedal... 124 00:08:22,933 --> 00:08:24,300 now you're in control. 125 00:08:24,300 --> 00:08:27,742 Restore control, great. Turn the steering wheel to the right... 126 00:08:27,742 --> 00:08:30,581 press the button to switch lanes 127 00:08:31,506 --> 00:08:34,655 See? The car switched lanes on its own. 128 00:08:35,250 --> 00:08:37,250 and accelerates to... 129 00:08:37,353 --> 00:08:39,353 Yes, that's OK. 130 00:08:39,391 --> 00:08:41,391 Now it'll brake a bit. 131 00:08:41,745 --> 00:08:44,033 decelerates to 60 km/h. Press the button again to switch... 132 00:08:44,708 --> 00:08:46,708 No, now you've cancelled it. 133 00:08:47,341 --> 00:08:50,100 Aha. That was a good example. We'll talk about it in a moment. 134 00:08:52,288 --> 00:08:54,854 So basically, that's autonomous operation. 135 00:08:55,053 --> 00:08:55,503 OK? 136 00:08:55,926 --> 00:08:59,900 Here's one thing I saw on the way. 137 00:09:01,377 --> 00:09:05,623 Any time you initiate Control on a public road, 138 00:09:05,888 --> 00:09:09,499 we always, always make sure we're as centered as possible in our lane. 139 00:09:09,843 --> 00:09:11,843 and driving under the speed limit. 140 00:09:11,959 --> 00:09:13,533 There's a very simple reason for that. 141 00:09:13,779 --> 00:09:18,167 Beforehand, you weren't entirely focused, you activated it and it deviated a bit. 142 00:09:18,303 --> 00:09:22,391 The danger in that is that let's say a motorcycle sees that and tries to pass you, 143 00:09:22,510 --> 00:09:25,300 that you're at a bit of an offset, and tries to pass you, you might react to it. 144 00:09:25,820 --> 00:09:30,428 Again, the system will prevent that, it will prevent a collision, but... 145 00:09:30,428 --> 00:09:33,801 you know, to be nice and to avoid startling the driver, 146 00:09:33,959 --> 00:09:35,621 we attempt to avoid this. 147 00:09:35,846 --> 00:09:39,933 And if we're far beyond our speed profile, and we try to activate, the car could brake. 148 00:09:39,958 --> 00:09:42,933 So again, if someone's behind you, that could be a problem. 149 00:09:42,967 --> 00:09:47,933 Now, I'll start sending you commands. 150 00:09:48,346 --> 00:09:50,900 What does that mean? That means... 151 00:09:51,433 --> 00:09:55,298 that we'll drive, and we'll begin at a rather low speed, 20 km/h... 152 00:09:55,298 --> 00:09:57,298 25 km/h... 153 00:09:58,340 --> 00:10:03,900 and at some point in time, one of the following things will happen. 154 00:10:03,949 --> 00:10:09,327 Steering wheel to the right, to the left, unwanted acceleration, unwanted braking. 155 00:10:09,644 --> 00:10:09,922 OK? 156 00:10:12,277 --> 00:10:16,667 I can tell that you it's quite hard to identify the acceleration... 157 00:10:16,933 --> 00:10:21,200 because we don't really have any speed profile, 158 00:10:21,467 --> 00:10:27,619 you don't really know if you're faster or slower than other cars... 159 00:10:27,674 --> 00:10:31,594 you will be able to feel the steering and braking. 160 00:10:34,192 --> 00:10:39,046 How do you think each of these errors needs to be corrected? 161 00:10:39,728 --> 00:10:40,839 Steering... 162 00:10:41,990 --> 00:10:48,280 First, brake, and of course, make sure no one will be affected when you brake... 163 00:10:50,058 --> 00:10:56,209 Brake, take control of the vehicle - OK - To try to cancel the vehicle's responsiveness 164 00:10:57,547 --> 00:10:59,880 So much for steering. 165 00:10:59,944 --> 00:11:04,325 And gas...apply the brakes and, of course, try to regain control. 166 00:11:04,571 --> 00:11:10,033 And for braking, retake control, and maybe put it back in autonomous mode, 167 00:11:10,093 --> 00:11:12,093 Or adjust your speed to the speed of the car ahead of you. 168 00:11:12,109 --> 00:11:15,714 - How do you disable autonomous mode? - Brake, steer... 169 00:11:15,753 --> 00:11:18,793 No. If you get a brakes fault. 170 00:11:18,880 --> 00:11:23,550 A brakes fault? Press on the gas pedal. - Full gas. - Yes. 171 00:11:23,550 --> 00:11:26,633 These cars, because they have automatic transmission and are hybrid, 172 00:11:27,106 --> 00:11:29,106 they react very late. 173 00:11:30,003 --> 00:11:34,501 So when you get a brakes fault, step on the gas, as quickly as possible. 174 00:11:34,723 --> 00:11:39,833 And remember, you only restore autonomous control once the situation has ended. 175 00:11:39,867 --> 00:11:45,833 -OK. -Even if it takes you another 5 or 10 seconds, or a few dozen meters more, 176 00:11:45,883 --> 00:11:50,193 you always make sure everything's OK, and reinitiate Control. 177 00:11:53,089 --> 00:11:55,034 Now, when it comes to braking during automatic steering... 178 00:11:55,344 --> 00:11:58,272 it isn't always necessary. -OK 179 00:11:58,788 --> 00:12:02,476 It isn't always possible, either. Depending on the situation. 180 00:12:02,555 --> 00:12:04,555 If there is heavy traffic around you, if someone is very close to you and 181 00:12:04,603 --> 00:12:07,555 the car suddenly swerves to the left, you won't just brake. 182 00:12:07,580 --> 00:12:11,779 Braking can also change with respect to this. 183 00:12:12,001 --> 00:12:15,300 I can tell you, though, that 184 00:12:16,496 --> 00:12:19,667 cancelling autonomous mode by braking 185 00:12:19,991 --> 00:12:23,759 is faster, because sometimes, there is some resistance from the steering wheel. 186 00:12:23,831 --> 00:12:25,831 I'll let you try that out, too. 187 00:12:26,045 --> 00:12:30,600 During a turn, I'll tell to turn the steering wheel very gently, 188 00:12:30,733 --> 00:12:31,833 against the direction of the turn 189 00:12:31,890 --> 00:12:34,733 and you'll see that it doesn't get released right away, it takes some time. 190 00:12:35,088 --> 00:12:37,088 With braking, it happens right away. 191 00:12:38,633 --> 00:12:43,431 So yes, the guidance is to always intervene, while correcting, by pressing on the gas or brakes, 192 00:12:43,455 --> 00:12:44,851 depending on the situation. 193 00:12:45,030 --> 00:12:47,030 These things don't always happen, in practice. 194 00:12:47,267 --> 00:12:50,467 because they aren't always necessary. 195 00:12:51,875 --> 00:12:53,875 Ready? - Yes! 196 00:12:57,857 --> 00:13:01,133 Ok, so you can already put it into autonomous mode. 197 00:13:01,633 --> 00:13:03,633 25 kilometers per hour. 198 00:13:11,059 --> 00:13:14,304 OK, so what we've just done was at 25 km/hour. 199 00:13:14,423 --> 00:13:16,804 The steering wheel turned to the right. OK? 200 00:13:17,677 --> 00:13:19,677 OK, go. 201 00:13:30,363 --> 00:13:33,967 OK, so what just happened is a gas reaction, it was slightly late. 202 00:13:33,967 --> 00:13:38,446 The car almost stopped entirely... - I helped it stop with my foot. -Yes. 203 00:13:45,029 --> 00:13:48,200 OK. Here, for example, you reacted well with the steering wheel, 204 00:13:48,200 --> 00:13:49,977 but there was no reason to brake. 205 00:13:50,136 --> 00:13:53,500 Our goal is, let's say this happened on the street, we want to keep driving. 206 00:13:57,517 --> 00:13:58,886 So keep the reactions as smooth as possible. 207 00:13:58,939 --> 00:14:03,421 Exactly. Minimize the traumas... Perfect. You see? Take it easy. 208 00:14:03,765 --> 00:14:05,765 OK, get into one of the lanes... 209 00:14:15,908 --> 00:14:16,543 Great. 210 00:14:17,257 --> 00:14:20,167 Yes, but here, too, there's no need to brake like that... 211 00:14:20,273 --> 00:14:23,600 so the idea is to minimize the drama on the road, 212 00:14:23,685 --> 00:14:27,347 and if the car suddenly accelerates behind something, brake gently 213 00:14:27,425 --> 00:14:30,501 just so you drive at the right speed. 214 00:14:36,638 --> 00:14:38,067 Aha! Exactly. 215 00:14:38,092 --> 00:14:41,992 So the goal is basically to identify when the car is veering from the lane. 216 00:14:42,020 --> 00:14:46,585 Now, the farther you look down the road, the quicker you can identify problems. 217 00:14:46,585 --> 00:14:49,600 and this is a good example of what happens when you have distractions in the car. 218 00:14:49,600 --> 00:14:53,133 And this happens a lot. We always have distractions 219 00:14:53,100 --> 00:14:55,400 because when you're driving, there are always developers sitting in the back. 220 00:14:55,504 --> 00:14:59,500 You drive with VIP demo passengers, people coming along for the ride, asking questions... 221 00:14:59,633 --> 00:15:06,245 and you have to respond to everything. But your top priority needs to be, of course... 222 00:15:06,589 --> 00:15:10,346 to look forward and maintain control of the car. Which, by the way, was great... 223 00:15:10,425 --> 00:15:14,129 What I did here was inject brakes and a steering wheel turn to the right. 224 00:15:14,287 --> 00:15:19,711 You corrected both, the gas reaction was great, the steering wheel correction was great. 225 00:15:19,869 --> 00:15:24,400 OK so what we'll do now is, I'm increasing the speed to 35 km/h. 226 00:15:24,900 --> 00:15:26,900 Ok, up to 35 km/h... 227 00:15:37,841 --> 00:15:42,300 Once you're within 10% of the speed I set... -Over 10%? 228 00:15:42,418 --> 00:15:44,567 10%. Either above or below... 229 00:15:44,700 --> 00:15:46,700 In other words, you activate, and immediately, it injects the commands it has. 230 00:15:46,836 --> 00:15:49,600 That's why you always need to activate it when driving less than 25 km/h 231 00:15:49,800 --> 00:15:52,600 or under the speed limit we set. 232 00:15:59,362 --> 00:16:04,967 Now, notice that the higher your speed... - The more the steering wheel... -Yes. 233 00:16:09,467 --> 00:16:11,467 We acted... -Both. -To the right and to the center... 234 00:16:12,739 --> 00:16:14,739 OK, let's make a U-turn. 235 00:16:15,755 --> 00:16:18,162 I raised the speed to 50 km/h. 236 00:16:23,770 --> 00:16:26,533 Now I'll adjust to 60 km/h. 237 00:16:39,033 --> 00:16:44,033 - I just set it to 75 km/h. - OK. 238 00:16:44,093 --> 00:16:47,533 This felt like a more controlled acceleration. 239 00:16:47,638 --> 00:16:51,950 Yes, yes... that's it. The speed profile is 75... 240 00:16:54,622 --> 00:16:58,100 so we're going along with it. Notice that all of the car's reactions will be gentler. 241 00:16:58,247 --> 00:17:00,700 See? So even though it's driving faster... 242 00:17:00,700 --> 00:17:04,067 Slow down a bit from 75 km/h, get to about 60 something... Good. 243 00:17:05,000 --> 00:17:10,033 So even though you don't need to do too much to move the car at these speeds, 244 00:17:12,467 --> 00:17:18,133 so until reaching 75 km/h, the car should speed up normally. 245 00:17:22,332 --> 00:17:27,316 Good. Wait, don't let it... don't let it. 246 00:17:27,300 --> 00:17:29,300 Now, activate! 247 00:17:29,539 --> 00:17:36,602 Again, 75 km/h... -It's from the steering wheel. -Nope. - No? 248 00:17:36,682 --> 00:17:40,167 Really? To me it felt very close... - No, nothing happened. -OK. 249 00:17:40,479 --> 00:17:48,700 My recommendation is...make a U-turn... don't keep your hands here... 250 00:17:48,700 --> 00:17:54,933 because that will make you work with just one hand, 251 00:17:55,067 --> 00:17:57,067 I noticed that this is something you do... 252 00:17:57,110 --> 00:18:02,507 So, if the car takes you to the right, you correct with your left hand, moving to the right... 253 00:18:02,666 --> 00:18:07,333 It's always, always better to pull the steering wheel instead of pushing it. 254 00:18:07,401 --> 00:18:10,133 because the muscle used for pulling is much more sensitive and accurate 255 00:18:10,133 --> 00:18:10,933 than the muscle used to push it. 256 00:18:11,502 --> 00:18:16,467 And in general, I use two hands, and if something happens, I correct with both hands. 257 00:18:17,221 --> 00:18:21,500 Brake! - Oh, drat. But I caught it! -Great! 258 00:18:22,168 --> 00:18:25,600 I didn't expect you to surprise me in the middle of a U-turn... 259 00:18:25,872 --> 00:18:30,267 that you'd run amok on me, but I think that the most important part of this exercise. 260 00:18:30,343 --> 00:18:34,633 Stop... You can't anticipate anything, at any point. That's the point. 261 00:18:34,767 --> 00:18:42,933 And the more monotonous and dull the trip, 262 00:18:43,267 --> 00:18:45,367 the greater the danger. 263 00:18:45,549 --> 00:18:49,900 But these are things that can cause a bit of drama around you... 264 00:18:49,967 --> 00:18:54,412 and we're trying to attract as little attention as possible, and minimize any drama... 265 00:18:54,412 --> 00:18:58,697 since any of our reactions could have a great impact on what's happening... behind us. 266 00:18:58,883 --> 00:19:06,569 Most probably, we won't cause an accident, or fly off into the curb or off a cliff... 267 00:19:06,533 --> 00:19:08,533 or collide with another car... 268 00:19:08,553 --> 00:19:12,333 but we might produce some drama behind us and that's something we'd like to avoid. 269 00:19:12,333 --> 00:19:15,633 That's why the gas reactions, when the car brakes when it's not supposed to, 270 00:19:15,833 --> 00:19:18,367 are very important, to deal with the situation... 271 00:19:19,552 --> 00:19:26,967 If the car swerves left, correct it, but not in a way that causes us to shift to the right lane 272 00:19:27,204 --> 00:19:29,933 and push the car next to us into the curb and so on... 273 00:19:31,367 --> 00:19:35,700 But this is exactly what it's about, when we don't anticipate something somewhere, 274 00:19:35,745 --> 00:19:39,367 and it happens, so we always need to stay focused. 275 00:19:39,633 --> 00:19:49,933 We're still driving at 65 km/h. I've raised the speed to 80 km/h. 276 00:20:13,940 --> 00:20:20,100 Here, here I accelerated... - I let it continue, until I felt secure... - Great. 277 00:20:20,100 --> 00:20:23,833 Everything's fine. The reason it veered a bit to the right is under-steering. 278 00:20:25,770 --> 00:20:30,267 Because of centrifugal force, it's too fast for it, the car isn't able to take control... 279 00:20:30,294 --> 00:20:34,200 so it has limits... both the limits we set, control limits, how much we can resist... 280 00:20:34,467 --> 00:20:39,580 with respect to the turn... and physical limits. You can't accelerate as much as you want 281 00:20:39,844 --> 00:20:41,844 when turning. 282 00:20:42,833 --> 00:20:47,033 OK. We'll do one more round-trip now. 283 00:20:47,220 --> 00:20:54,933 Now I'll set it for 80 km/h. I want us to drive a bit fast when turning, and feel the car... 284 00:20:54,945 --> 00:21:01,867 So, without surprises? -No surprises, feel the car... see how it behaves... 285 00:21:03,300 --> 00:21:09,567 Mainly here in the turn. You can see that it isn't smooth. There is a line that's a bit odd.. 286 00:21:09,628 --> 00:21:13,386 Was that you? -I don't know, you tell me. -Doesn't matter, but I'll take control. 287 00:21:13,411 --> 00:21:16,533 -No problem! I'm with you. I trust you. -Let's go. 288 00:21:17,933 --> 00:21:21,267 There! Did you see what just happened? -Yes! 289 00:21:21,633 --> 00:21:25,100 You took off your hand for a second, started feeling comfortable, and then... BOOM. 290 00:21:25,100 --> 00:21:27,089 291 00:21:27,116 --> 00:21:33,200 OK, so what we've just experienced is situations that probably won't happen on the road... 292 00:21:33,533 --> 00:21:37,433 but it's important to know what the car can do. 293 00:21:38,000 --> 00:21:40,000 because we've just worked on the limiters. 294 00:21:40,200 --> 00:21:45,633 And if, God forbid, there's a bug or something that isn't right, 295 00:21:45,633 --> 00:21:51,100 we could end up with the car reacting like this, 296 00:21:51,200 --> 00:21:54,533 with the brakes, the accelerator or steering. 297 00:21:54,706 --> 00:22:02,000 One thing we could see here, very clearly, is what happens when we're distracted. 298 00:22:03,833 --> 00:22:06,533 Yup. A split second of inattention 299 00:22:06,853 --> 00:22:10,600 translates into a delay of several tenths of a second in our reaction. 300 00:22:10,600 --> 00:22:11,986 It's significant. 301 00:22:12,039 --> 00:22:14,039 It could be a situation where... 302 00:22:14,076 --> 00:22:18,933 I wouldn't say... worst case scenario, it could lead to an accident... 303 00:22:18,996 --> 00:22:25,600 In a more moderate scenario, it could cause some drama around us, startle people... 304 00:22:25,625 --> 00:22:31,582 as opposed to keeping things smooth and just going on, as if nothing happened. 305 00:22:31,800 --> 00:22:34,267 That's what we're really after. 306 00:22:34,433 --> 00:22:39,100 Even if we've made a mistake, even if we've braked, even if we veered a bit from the lane, 307 00:22:39,100 --> 00:22:41,786 we continue calmly. 308 00:22:45,622 --> 00:22:51,071 That's it, basically. That's our driver training, conducted in a closed-off area. 309 00:22:52,500 --> 00:22:56,300 And the real thing is when we're driving on the road.
