Making a car difficult to steal

Car theft often does not involve actually starting the car. Driveshafts can be removed and then the vehicle can be towed or pulled into or onto a trailer. These are cases where just about no matter what you do, they will still steal your baby. So what came to my little mind was a form of line lock. Possibly an electric system that could charge and hold pressure so that all the wheels would be locked. I'm not sure this would be possible and I know that if someone really wants your car, they will still get it. Just thinkin'!
