Regarding electric scooters, I’m not really sure what bits there are to be flipped, which could cause issues. My understanding is that when you hit the brakes for example, that electrical signal is sent directly to the brakes, and there’s not a digital buffer of inputs which are stored to memory to be read, which is where a bit flip could happen. I assume braking and acceleration are analog voltages on the wire, so a brief cosmic ray would be miniscule and probably not noticeable.
