Not even in US, it's really common in any part of the world. Accidents are really happening every time and moment because of the people trying to be over smart and showing off their smartness which often leads to such stupid acts.
Recently my somewhat nearest relatives also died because of this, two boys where going through some car race in the middle of a road between midnight and they were attending their party they just reached to open their car and the racing boys just hit them so badly that they died.!
Ugh that is horrible. I am sorry that happened to your family. I will be happy when self driving cars are the norm. I fully trust a computer over most of the crazies out there!
