Beyond 30yr the people driving them are doing it for fun and aren't going to generally be running bald tires down the highway in the rain and when they do they are doing it full well knowing that they have to be super careful. Basically they know what they're getting into and don't need the state to tell them why working lights are good and brake pads shouldn't make metal noises.

This hardly matters though because you don't need to register the vehicle in the state you're living in.
