A year or two back there was footage of a bloke driving a bus along a freeway at stupid mph & he was so engrossed in his phone for an absolute age before looking up a second before he hit the back of another vehicle. I don't know about America but here there's been a few incidents which have never been fully reported in the press. Everything seems to go very quiet - I think they don't want to further upset the family of the one who caused the smash.
At the end of the day though, if someone caused a smash & people died then it should be put out there as a warning to others.
