Insane? This is just what stealing a car was like in 1970. If you get the ignition to turn, you've stolen the car. If you're dependent on technology to stop vehicle theft, you've basically already lost. At the end of the criminals will just use a flatbed tow truck to steal the vehicle if it is worth enough.

The "immobilizers" you're referring to are the bane of my existence from my perspective. Instead of getting cheap $5 copies of my keys made, I have to pay something like $120 to Ford to get copies made.
