> There's no such thing as a secure system I mean, in modern vehicles you can pretty much get there, but you might have to give up some features. For example, walk up unlock. You need to push a button somewhere to make unlock secure. The way you get there is through FIDO. Have the engine controller ask the hardware key to confirm who it is through a handshake. Don't start/enable the engine if that handshake fails. With that in place, the route to theft involves removing/replacing the engine controller which can be a major pain to do fast. Cars with bad security systems generally involve pulling the steering column off and touching the right two wires together to start then engine. That said, preventing theft of the contents of a car is impossible. Windows break easy and it's stupid easy to push the unlock button. That can't change.
