I'm sorry but is everyone here sucked into the "reality-distortion field" that Tesla Auto Pilot seems to be generating? Nothing happens in this video that a competent driver wouldn't have done. Detailed Explanation: In the UK part of the driving theory test is a "Hazard Perception"[1] exercise that test candidates awareness of hazards around them by playing short video clips and getting the candidates to click when t…

You comment describes exactly why this is so amazing - the autopilot executes the same as a competent driver! It's magic because it's the first time in human history that we've had such skills available in a car autopilot. It's like saying cruise-control is worthless because any competent driver can maintain their speed - you're missing the point. We're achieving parity between autopilots and human drivers, except th…

>You comment describes exactly why this is so amazing - the autopilot executes the same as a competent driver!

I can agree with this. Too bad it isn't the default sentiment instead of over-the-top optimism or cynicism.

I don't think anyone here is surprised that people get into stupid, easily avoidable car accidents all the time. The argument seems to be about where the technology currently sits. In this video the Tesla braked and avoided rear-ending the colliding cars; so did the vehicles with no autopilot in the right lane. This is "impressive" to some people, but it's also the bare-minimum level of acceptability for self-driving vehicles.

The car responding faster allows for a less steep braking, which makes a rear-end less likely as the car behind you has more time to react (even assuming it doesn't have auto-pilot).

This is why I always try to brake early and long. Nothing annoys me more than drivers leaving it to the very last second, giving the person behind them as little time to react as possible.

This is also why I don't like to engine brake on the freeway.

Working as well as a "competent" driver (which, as we all know, is already a high bar) is a fantastic first step.

My car, with myself and a friend inside, almost got ran over by a truck when the driver didn't even bother to slow down for the yellow light and crossed at high speed the red light. Luckily he didn't hit anyone. I totally agree with you.

I don't know your situation, but my experience driving big heavy stuff is that sometimes a yellow light does not provide enough warning to stop 55mph * crazy weight, and you sometimes find yourself with a dilemma of entering an intersection just after a light has changed, or a few seconds after the light has changed.

It sounds to me like the driver shouldn't be going 55mph in the first place, if they can't stop before the yellow light turns red.

It's similar to icy roads. If you go the normal speed limit and you slide into another car, it's your fault. The fact that the speed limit was higher than your speed doesn't release the driver from responsibility.

Just brilliant technology at play there. I had to rewatch a couple of times to really grasp how early the Tesla recognized the emergency braking scenario.

One thing to note is that most dash cams, mine included, shoot at a fairly wide angle. The Tesla was likely following a good bit closer than it appears from the video alone.

This is also an interesting visual demonstration of why that Armco barrier between the opposing directions of traffic is so terrific. It's quite possible that having that in place saved several lives in this accident. It clearly absorbed some of the impact energy and prevented the SUV from crossing into oncoming traffic.

The UK driving test is significantly more rigorous than the US, and it shows: UK drivers are amongst the safest in the world (2nd lowest road fatalities per 100k people; top five per 100k vehicles). The US isn't even in the top fifty (and for calibration to the American reader: Canada is in the top 30, but hey, at least the US beats out Mexico). At the end of the UK practical examination process I would expect all new drivers to be "competent" by this standard.

My mom got in an accident due to driving too close to the car in front of her. It caused me to really take heart to my Driver's Ed teachers word of wisdom to always leave enough space in front of you to be able to safely brake to prevent that. I wish everyone would do that. It also makes driving in traffic less stop-and-go

yeah i try to do that but then other cars just merge in between the space i leave in front of me and force me to be on their tail. meanwhile the guy behind me never leaves enough distance either. safe driving doesn't mean anything when others drive recklessly

Precisely the problem.

Safe follow distance isn't an evolutionarily-stable strategy. The number of accidents avoided by people following it is more than offset (at least psychologically in the minds of the drivers) by the perception that people are constantly cutting you off if you adhere to it. Since punishments for failing to adhere to it are few and far between, drivers get sloppy.

It's the sort of thing you could, however, program into a robot and expect the robot to adhere to it.

Other peoples poor driving shouldn't make you drive worse. In the Drivers Ed classes I've taken, the recommended advice is that if someone is tailgating behind you, you should leave EVEN MORE space in front of you so that if you need to hit the brakes, you won't have to hit them as hard and thus won't be as likely to be rear ended.

and then pushed into the car in front of you.

Same reason to use the handbrake at a crosswalk/zebra crossing: You don't want someone reckless behind you to make you cream some poor folks.

> There is NO AUTO PILOT MAGIC IN THIS VIDEO I think we'd all agree this isn't magic; the point is that it works in spite of the driver. A "competent driver" is going to be especially alert during an exam, but over the course of countless errands and commutes, their guard could be down, their reflexes may suffer due to lack of sleep, etc. Autopilot doesn't get tired, and never lets its guard down. That's what matters…

I think you may have misinterpreted my comment.

My intention was in no way to underplay or diminish the achievement of Auto Pilot but to simply make the point that: In this video, of this event Auto Pilot adds nothing. In this case the driver was "alert and competent". This video does NOT showcase or demonstrate Auto Pilot preventing an accident, reacting faster or better than a human.

That is my point. People seem to be extolling how Auto Pilot saved that day in this video. It didn't.
