Earlier quoted context omitted.
I disagreed with you and went looking in the article for evidence (yeah bad, epistemologically). I actually found evidence for your point. The largest cause of fatal crashes is Generally distracted or "lost in thought" (daydreaming) at 64%. That happens to most people,.
How many of those 64% had their accident because of phones/drugs/recklessness and claimed to be distracted instead? With all the liability and shame involved in fatal crashes there's absolutely no way people are going to honestly self report illegal behavior.
Hopefully police are figuring out that one of the parties in the accident is high while they do the interview.
