Because for someone to believe the ability to stall a moving car is ok is for them to believe the passengers are potential acceptable losses. No, it only requires them to fail to test that their device cannot be used to shut off an operating car. Stop and think -- what criteria define an "operating car"? It's not "the car is on" since it's entirely possible to stall out while moving. It's not "the car isn't moving" since that doesn't cover the stoplight situation. It would be trivially easy to code a device that would not permit the car to be restarted even if the car stopped in a dangerous situation.
