I'm wondering when the Tesla beeps if it reacts to the behavior of the red car or instead to the cars braking in front of the red car?

It reacts to the car breaking in front of the red car - the trick is to use radar reflections of both the red car and the one in front of it, which propagate below the red car. This feature was advertised with a recent firmware update.

I have seen plenty of 3 car accidents and the last car involved in the accident is purely because it could not brake on time and the first 2 cars involved in the accident are due to human stupidity.

I live in Dubai and it is a mix of many cultures and people drive like crazy here, I have seen a single accident involving 6 cars because most of the rash drivers will drive tail-gating

At least Dubai really needs lot of Tesla cars to avoid such accidents which are very common here
