BMW has invented an automatic parking system:

The luxury carmaker's parking-assist technology will park your car for you as you stand outside and watch, according to BMW during the demo of a working prototype at its Munich headquarters this week.

All you do is press down on a remote-control button and your Beamer parks itself.

(Link includes a video.) The system is nice, but I'd love to see a more advanced version that can handle parallel parking in a tight space.
