Hank "Halloween" Murphy is a character in Cars.
Hank used to get into a lot of trouble in his younger years, drag racing, doing donuts, even playing chicken with his friends. Hank never lost a chicken race because he had problems with depth of perception. He couldn't tell the other cars were getting closer, only that they were getting bigger. He decided it was time to stop goofing around when he lost a curb feeler in a race. That was just a little too close.
