Prius is not stolen much because it has no ignition lock, and you cannot hotwire the car. To use the car you need to have a keyfob. A thief can carjack you or steal the keyfob, of course - or he has to rent a flatbed truck and drag the car, with locked front wheels, onto it. Then it is only good for spare parts.

Some computer scientists came up with a way to attack encryption that the keyfob uses. However it remains just a theoretical possibility, since any thief who is smart enough to use this very complex technology wouldn't be stealing cars. Also the thief would have to intercept a brief radio communication between the keyfob and the car when you unlock it. This makes it useless for theft of a random car that the thief encountered in a parking lot.

Right - he'd be selling the tech to car thieves...
