1. Have an emergency break button somewhere in the car that the user could press at any time to have the vehicle break. Note that we already have those in all trains, buses etc. 2. Have a warning light up next to the button asking the user to press the break button as soon as they feel safe to do so. Note that we already have those service lights in all regular cars. Simply add a buzzer as well for people asleep etc. 3. ‎Have the circuit that breaks upon button activation be sealed off from the internet (make it hydraulic). The only action of the "good C&C" is to turn a light on.
