It was the scariest night of Andrew Grantt Conlyn's life. He sat in the passenger seat of a two-door 1997 Ford Mustang, clutching his seatbelt, as his friend drove approximately 100 miles per hour down a palm-tree-lined avenue in Fort Myers, Fla. His friend, inebriated and distraught, occasionally swerved onto the wrong side of the road to pass cars that were complying with the 35-m.p.h. speed limit.

"Someone is going to die tonight," Mr. Conlyn thought.

And then his friend hit a curb and lost control of the car. The Mustang began spinning wildly, hitting a light pole and three palm trees before coming to a stop, the passenger's side against a tree.
