There was just an incident in my area that involved OnStar shutting down a hijacked car at the police’s behest and the guy got out and shot and killed another driver in the attempt to carjack him. So, any car with OnStar apparently already has a remote kill switch. Perhaps they needed the owner’s permission first?
