It's like in 40 years a toaster or an oven keeps running if you don't disable it through your "home controlling mental device" and burn your house to the ground while you are sleeping. Oh, and you cannot opt-out of the "mental device", you have to use it like it or not.
Old people have the mental muscle to think "I have the car keys with me, therefore the engine is off" built after decades. It's a serious design flaw to not offer at least an opt-out for these people (like key not IN the car, engine shuts off).
