It's nice to know that Tesla can do that, but sorry, I just don't see anything "magical" in this video -- speed wasn't that high (~110 km/h), the gap was quite wide and the two cars on the right lane also managed to pull over and stop in time too. I have personally avoided much closer encounters driving both car and a motorcycle. In such situations, you should pray that there's no truck behind you.

Did you not hear the warning tones trigger before the accident occurred?

I watched a similar video recently, but a car ahead avoided an accident and the car where video was taken from was rammed in the back because of a sudden stop. Which make me think maybe Tesla's response wasn't the best possible.

Link?

The Tesla would be aware of the cars behind it as well, so this sounds unlikely

Right lane cars can see breaking SUV, you can't from this POV. This could be the moment you reach out for the candy, check the thing on the right seat, or even check the rear view mirror longer than usual and 1/2 seconds will all it takes at 110 km/h.

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.

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).

It wasn't a Tesla, couldn't find a video unfortunately.

What puzzles me here is that the SUV flips over after being hit in the right-rear corner by a relatively small car and bumping into the side barrier. Flipping over in a case like this looks more likely to happen to an SUV than a lower-centered car, and makes me question the safety of SUVs.

This is great video to study on many levels beyond self-driving car. Some observations:

* The car behind didn't show turn signal so probably driver wasn't paying attention.

* A small car escaping with not too much damage while SUV rolls over many times

* From physics point of view, the car behind produced almost perfect torque that started horizontal spin on SUV

* Collisions with barrier at high speed can produce lots of rolls. Many time we see cars upside down in accident and wonder how did that happened. This is how.

* The middle barrier did its job wonderfully even against massive inertia of SUV. Cars on other side remained unscathed!

This is a commonly known problem of SUVs, their center of gravity is a lot higher so they're a lot easier to flip over. That's why I'm puzzled by people who buy urban SUVs, that is, jeep-like cars that they never intend to use off-road.

Isn't that because the Tesla can see the brake light on the car two cars ahead? As soon as the red car swerves slightly to the right, and the brake light becomes visible, the Tesla brakes. Moreover, the speed of the cars before it are suddenly slowly down.

Is the assumption here (flipping over = very bad) correct? Is it possible that [edit: the force] can dissipate more easily if it flips (provided the car is built correctly to withstand the force of a flip)?

NB: I know nothing about this topic, genuinely curious to hear from someone who does.
