I would also recommend anything by Sebastian Thrun on the topic of autonomous cars. His Udacity course is a great starting point, and it inspired me to do my graduate thesis on an autonomous car simulation.

If anyone is looking to get a little deeper, check out some of his literature during his time at Stanford:
