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
