> 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 underestimate the ability of the trucking industry to poorly maintain automatic pilot systems.

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

But at least if it's a poorly maintained driver the company can blame the driver and not change their practices.

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.

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.

Some were arguing yesterday that there'd be a strong negative emotional response when a driver-less car causes someone to die. I hope there will be an equal and opposite reaction when people are saved by this technology.

There won't be.

I'm not sure what you mean by "the car behind didn't show turn signal". If you're referring to the pink hatchback that ultimately rear-ended the SUV - the pink hatchback seems to be making a lane change to the right after passing. The driver seems to have signaled and looked to the right to clear his/her blindspot at the same moment the SUV ahead slams on the brakes. It really seems like bad luck, that traffic would…

Well no -- that wasn't bad luck at all. He simply was way too close for the speed. Back in the day when I got my driver's license we were told to have 3 seconds of distance. One second to react one second to brake and one second for safety, if I remember correctly.

Around here they recommend 2s. As part of a science fair project, I measured the following distance of cars on a nearby highway. It's been about 15 years but IIRC, the mode was ~0.5s.

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 the autopilot will never be distracted or tired, and always operates with the skill of a competent driver (and many drivers are not competent).

Very impressive demo. I guess this is possible due to great sensors (radar/lidar), computing power (tesla has the most computing power in a car) and good trained deep nets and algorithms (again tesla,cruise & waymo have the biggest investment here)

Does anyone know how I can get my hands on a nvidia drive PX2 board and a quanergy lidar? It seems the lidars and such nvidia boards are only sold in huge quantities to auto makers and not as single units available for people to make their own robots.

> why does lately every Tesla-related post have a token "PR stunt" comment? Why does every single bit of Tesla "news" make the front page? I see 50 videos a day on Reddit of people miraculously avoiding accidents, never once on HackerNews. This is kind of cool, but I'm going to remain skeptical that it "predicted" the accident. There were other cars that also stopped in time. Did we expect it to bulldoze into the bac…

> I mean, do people actually believe that Tesla has developed self-driving AI that is actually "predicting" accidents? I don't understand what would be difficult to believe about this. It doesn't take super-sophisticated math to predict car X and car Y are too close and moving too fast to avoid an accident. It's mostly a matter of having the sensors to build an accurate map, and it seems like Tesla has that.

>I don't understand what would be difficult to believe about this.

It seems like it could instantly react to the car in front drastically changing speeds (read: colliding with the car in front of it), and brake immediately. But predicting seems like a different issue, with far more false positives (Tesla hitting the brakes when it anticipates a potential collision). Is that happening?

You could be right, but this video certainly hasn't convinced me.

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

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.

No way. I use semis as a highway safety feature. They can see farther down the road and are much less likely to get in an accident statistically. When visibility is poor, I follow one (with a large follow distance).
