This Q obviously applies to self-driving cars where all driving rules are pre-programmed into the car's computer. Seat belt off? The car will refuse to start. Trying to exceed the speed limit? The car will not respond. ETC.
BMW already feature this technology in their newer models where the cars engine can be remotely disabled by sending a cellular signal. Or the car can be started. Most car rental companies are incorporating this technology.
A recent police chase ended with a simple radio call from the Traffic Officer to Central control where they sent a signal to the offending car and turned off the engine.
