There was a bad limo accident in Detroit almost 20 years ago. It involved about 5 Red Wings players who were out celebrating about a week after they won the Stanley Cup. They were all in a limo and a drunk driver hit them. Several of the players had career ending injuries. I was pretty sure after that accident, legislation was passed making seat belts in limos mandatory. although, maybe that was only a Michigan law.
Also, to the PP, the limo driver might not have been at fault because in some states, u-turns are legal.
