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.
"speed wasn't that high (~110 km/h)" -- That is as fast as you can go on major roadways here in Brazil> I would say it is pretty fast...
" In such situations, you should pray that there's no truck behind you." -- So true. Wouldn't the autopilot account for that before braking that fast? It would cause a much bigger problem if not...
Where is that? Where I live there is a 100km/h limit, and the local police sometimes post on social media when they ticket someone going 160km/h+.
That said, 100km/h made sense in 1970, but now with the safety of modern cars, there's no reason that 130km/h shouldn't be the standard everywhere modern cars are prevalent.
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.
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.
