And so was he. The first talking you hear is them telling the kids to stay put until they're sure no one is going to be rear ending them. Does anyone know if these braking systems account for people driving behind you? And if a collision is inevitable, what do they "choose"?

Well I would hope it would choose getting rear ended, particularly because that is the fault of the driver behind you. If you choose to slam into someone instead of letting someone slam into you, you are now at fault.

I dont think the driver would like to have a whiplash...

> software update enabled Teslas to “see” through vehicles traveling immediately in front of them. In this case, however, the Autopilot seems less like X-ray vision and more like straight-up clairvoyance

I don't believe the car is clairvoyant, but my guess is radar bouncing off the asphalt under the cars. And maybe a glimpse of the brakelights?

When the car is motionless (e.g. immediately after it has come to a stop from the emergency breaking), does the computer engage the breaks just soft enough so the car stays put? And would this reduce the impact from behind if it were to happen?

I'm curious if you really want the brakes on full when you get hit from behind. It seems the cars would start to crumple in place until firmly together and you overcome friction, getting launched. With the brakes off, you would immediately accelerate, but perhaps with a lesser initial burst. That's the decision I had to make one day. I saw a car coming to hit me from the rear. I took my foot off the brake and gripped…

The opposite, you should release the brakes to reduce the effect of the impact so you actually acted correctly.

I expect an autopilot could deal with that situation much better than a human as well. It should be able to predict if the car behind won't stop. Certainly better than a human driver could (if the human would even notice the car coming from behind with that happening in front). Then, assuming there is some space open in front, as there was in this case, it could accelerate to avoid the collision from behind. Now I'm…

I think the consequences of this would be too significant for Tesla to silently implement. Given an unavoidable rear crash, it could cause a multi-car accident and increase the collision's severity relative to braking.

Doesn't Tesla record the video of the traffic via its array of cameras?

Does a Tesla continuously record all conversations within the vehicle? The sound recording is clearly from before the warning beep of the impending crash.

The video is from a third party dash cam.

Thanks for pointing that out.

Don't understand the downvote. It was a simple question from someone who is concerned about (online) privacy.

I thought this an interesting video when Elon retweeted it. Basically the car is responding faster than the people do and keeping things from escalating. That said, having been on 101 when the cars in front start dancing like that I have to say my biggest worry isn't stopping in time its having someone behind me not stop.

Because Tesla brakes faster than a human in this situation, it doesn't have to brake as much, it can slow down in a timely manner.

I was very confused about this video until I watched it with the sound on. The Tesla beeps at the driver clearly before the accident has occurred, but doesn't appear to decelerate until afterwards.

After watching the footage several times, it seems to me like the car is breaking either just before or immediately at the point of impact, certainly way faster than a human driver could. What I'm curious about is whether the autopilot predicted the crash due to the relative speed of the two cars ahead of it, or if it was reacting solely to the change in speed of the car that braked.

If you look through the red hatchback you can clearly see the brake lights of the 4x4 go on (visible from 0:02, though not yet clear), and brake hard to a stop. The hatchback barely seems to react..
