I've seen cars that are capable of parallel parking on their own. A local dealership here did a demonstration of it on YouTube a while ago. It was a 2012 Ford Focus that they used in the demonstration.

Car parks itself! (chance to win one ...) - YouTube
I couldn't see what the passenger was doing. Suspicious!
Nawww, I know they have cars that do this. Cool!
