Speed and control. People are bound to make mistakes. Accidents are due to mistake of humans.
So, we need a change in the way we travel, subways, monorails are generally safer, automated driving cars or other form of transportation are the only option we are heading to.
I think the main course is luck of respect of motorist to there fellow driver especially in rush hour or traffic the heat of the vehicle will fast thrue the head of the motorist the end is road rage..the best we have to do is respect each other and always remind your self that having a licence is privilege and not your rights..
