I would say distraction is "behind" most car crashes, but so are alcohol, drugs, speed and impatience.
As I drive to work, I see people that are clearly distracted, but even worse they are going 15 over the limit, cutting in and out of traffic and the statistics show those who end up crashing are very likely to be intoxicated.
I worked in a body shop whose owners son picked up parts in a nearby city.I almost was fired because I would not ride with him.He used to read the newspaper!
