I think this should be mandatory every couple of years or so in order to renew your driver's license.

On the day I applied for my license, I visited my dad at the hospital and the guy next to him had a smashed face from a car accident. He had been in a car with a friend, who was driving, and his teenage girlfriend, who was pregnant. The girlfriend's baby died and it was considered unlikely that the girl would survive. The driver went mostly unharmed and was understandably very upset.

I swore that day to always remind myself of this before I get into a car. I used to, but now I don't. The impression fades.
