I see they have over 43,000 parking spaces as of 2008 (lots of parking structure add-ons), so a car burglary every 15 hours sort of signals to me they're doing something right. I'd expect much higher numbers than that across the whole system with that amount of vehicles. I'd be more worried about auto theft, particularly if you have one of those hot new Camaros that are disappearing or older model Hondas that seem quite easy to steal.
