This isn't an argument for absolutely any cost one should choose to impose. I had a hard time finding exact stats but one should I think assume that less than 1/10th of 1% of cars have such a device installed. This means that one is installing 1000 devices for each one in use. It should make more sense to me to provide a means to communicate with such a device wirelessly and software support for making starting contingent on such communication.
