Why is this such a big concern? Why not a concern about those hack into the security system and steal your car? It's even easy to do with the right tools. And full scale GA airplanes (the smaller ones) are even easier. The door lock of many is a lock similar to your desk lock. And the ignition of many are no more complex than a 1950's automobile, you just pull the wires out the back and cross the right wires. So why are full scale manufactures not required to do something about that?
