Probably no other vehicle because they have paint and clearcoat so the iron particles don't come in contact with metal and thus the reaction doesn't happen. However it still sticks to the paint too and needs to be cleaned off regurlarly. If you go buy a bottle of fallout remover and spray it onto the doors of your vehicle you're going to see a ton of pink streaks indicating iron contamination.

I've personally not owned a single car that haven't had rust on it. And not just on the surface but the panels literally rusting thru. This will never be an issue with cybertruck.
