Not just a competent driver, but a competent driver that is primed to be looking for a hazard in a short video clip.

Saving any lives in great, but trucks are a very small part of the problem. Out of 33883 US traffic deaths in 2009, 3380 involved trucks, and truck driver error was listed as a cause 26% of the time. Self driving long-haul trucks probably won't save "thousands" of lives, but certainly hundreds. http://www.trucking.org/ATA%20Docs/News%20and%20Information/...

The 26% statistic is misleading in this case-- just because the death didn't involve truck driver "error" doesn't mean a different movement pattern for the truck wouldn't have made a difference. For example, in the original video, if the Tesla autopilot hadn't braked, and the car had been involved in the crash, it's not clear to me that error on the part of the Tesla driver would have been listed as a cause.

It should be, though. Car #1 stopped shorted and car #2 hit it. Car #2 was at fault for hitting Car #1.

Car #3 (Tesla), if it didn't stop, would be at fault for not maintaining stopping distance, hitting Car #2.

A nice sci-fi trope is that the unpredictability of humanity, and when/how it will "fail" when something better would "succeed", results in the preservation of humanity itself. It's nice to consider in the wake of the elitism.

Well, I think there's something to the notion that there is value in humanity, in spite of--or perhaps even because of--its flaws and non-binary approach to the Universe. And, of course, there's the whole "I Robot" deal, wherein the robot elects to save the life of the adult vs. the child based purely on a sterile odds-of-survival calculation.

That's not really what I had in mind with my comments here, but it is an interesting point.

And maybe it is another reason to consider prudence as we rush headlong into a world increasingly reliant upon technology.

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

> 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.

Which is perfectly fine - it's safer that way. Not wanting to feel like a 'loser' is understandable - but when it is life and limb that's on the line; I know which side I'd rather be. On the other side is road rage and stupid games of chicken with your life on the line.

That's not a reason to use the handbrake over the brake pedal. Typically the brake pedal is more effective (all wheels, ABS) than the hand brake (sometimes 2 wheels, probably no ABS). The handbrake is just for emergencies and parking.

When I learned to drive in the US (Washington state) I received advice similar to that, however when I took lessons in the UK, I was advised that when you are rear ended, you will have a hard time keeping pressure on the break pedal so you should do both .

Fair enough.

Poorly maintained autopilots would still be safer than poorly maintained drivers.

Drivers maintain themselves, so this is pretty much purely maintained drivers vs. little-to-not maintained autopilots. That said, I agree there's plenty of incentives for the trucking companies to go the autopilot route.

>Drivers maintain themselves

Fatigue and sleep deprivation are chronic problems in the trucking industry. Clearly, many drivers are unable or unwilling to maintain themselves.

Icy conditions are maybe predictable (ok, it's under 0°C outside), but yellow light times (edit: the time between the light turning yellow and the light turning red) are not.

Yellow light turns are predictable in that you know that they'll happen, just not when. So if you have a heavy load or other adverse conditions you should slow down to a speed where you could stop at the correct distance. Software should do an even better job of predicting the weight to speed to stopping distance ratios.

You don't know how long the yellow light will last before turning red. That time is variable from light to light and essentially unpredictable to drivers.

> Nothing happens in this video that a competent driver wouldn't have done.

If you go by the street definition of driving competence, then you get exactly the accidents like the one on this video.

Safe driving distance. The primary thing most "competent" drivers don't give a fuck about. Second being speed limits.

And yes, I understand many people drive that way not because they want to, but because other drivers aren't leaving them a choice. Ironically, this area is already heavily regulated. What I believe is needed is much, much stronger enforcement of those regulations.

Yesterday, I was saying that autopiloted trucks would take over the long-haul trucking industries. This is why . Driver errors with semis on the highway kill thousands every year. This kind of technology will save lives - not just of the Tesla drivers (or other autopiloted drivers), but of the vehicles they don't hit.

It's not just driver errors. Apparently the crash detection system kicked in during the Berlin ISIS attack and stopped the truck before the attacker could kill more people (sorry, link in German) http://www.spiegel.de/politik/deutschland/anschlag-von-berli...

That's cool.

This seems to be a fresh news story but I hope it will be more widely disseminated. Among so much aimless hand-wringing over terrorism, security theater "designed to stop it", and dragnet surveillance and intelligence gathering, here is a clear example of a new technology reducing the impact of a terrorist act and saving lives.

It kinda goes against the click-generating narrative of autonomous driving technology being half-baked gimmicks rushed to market, fatal accidents waiting to happen, and Tesla and its celebrity corporation ilk flying too close to the sun on homemade wings.

> it's the first time in human history that we've had such skills available in a car autopilot

I doubt this assertion is true: lot's of cars with plain old cruise control can select a safe following distance and detect when the car ahead is braking. Roof-mounted LIDAR can see several cars ahead (and behind) and it would be negligent to to apply the same collision avoidance logic to car n+1
