In my opinion, the best anti-theft system, if the whole car got stolen, would be...
A system that detects that you are out of reach of innocent bystanders... then... IMPLODE
One device my previous boss was playing around with when he was working at the radar station up here in Northern Australia was a solenoid driven spike bed under the drivers seat.
Basically a small wooden board below the seat that when triggered would stab/jump up and down under the seat. The spikes/nails on the board would pierce the drivers seat and extend to about 2 inches above the top of the seat. Considering it can be possible to have this board pulse/jump at least once a second or more... It would kill them with in a few seconds from shock/bleeding and so on..

Everything else is pending for now as switched from a Mini-ITX setup
I'm waiting for one of these devices to false alarm whilst you're driving along. I hope I'm not nearby when it happens.
Old Systems retired due to new car
New system at design/prototype stage on BeagleBoard.
I would be too scared to even drive my own car... Spike strips, flame throwers, pepper spray, all that jazz, when in the car but disarmed is enough to deter the sane owner from driving. That one bad morning when you forget to press the override button and you get spiked/charbroiled/sprayed would probably be less than fun...

Not very legal in the states but I love it.
I would so use this if I thought I could get away with it.
I wanted to have my car dial my cell phone number in case of a break in so I could talk to the guy. But for added effect, the same charges they use to make fake bullet holes in walls in movies, put one in the pillar. "Hey buddy, that was a warning shot."
My favorite ever was still the car that auto-locks the doors and has lexcan windows so they can't be shattered. Though I imagine a crook would probably tear up the interior something fierce if he's trapped in your car.
