like a vehicle touching a body in a speed of 3/4 km/h and the kid shouting or stepping away? or worst case your motion sensor beeping?

how much the conversation diverts on a commentary about someone not wanting a car shipped with an OS capturing telemetry even of farts on the right back seat

This is one of those proverbial regulations that are written in blood. So no, that's not the worst case.
