In a parallel theme, I cried my adolescent heart out when the Dodge Challenger Brit Eckland was in drove into a locomotive.
Dirty Harry and Crazy Mary I think it was.
Hmmmm.....
I can't remember for sure, but I think there were a couple other people in the car.
The movie you're thinking about was “Dirty Mary Crazy Larry” (1974). Peter Fonda was Larry and Mary was played by Susan George. She crashed the car. It's said that “Smokey And The Bandit” ripped of several stunts and characters from this movie.
