> I apologize for any flame wars this creates, since people find driving to be deeply personal and any findings which may criticize their driving habits is generally frowned upon.

I appreciate your attitude here. Mine is opposite. Dangerous driving injures, maims, and murders both perpetrators and innocents alike. Criticise bad driving loudly and often. You might save lives. I had to tell my mother in law that her daughter, my wife, lost her life in a road traffic accident. There are few aspects to serious road traffic accidents that are not horrific, and speaking up may save lives. Every year, 1.19 million people die as a result of a road traffic accident. Between 20 to 50 million people suffer non-lethal injuries, many of those leading to disability.[1]
