There is a point I think most people are missing in this auto/health insurance comparison. In every state I know of, you can drive a car without registration, drivers license, or insurance as long as you stay on private property. The state imposes those requirements only on people who navigate the public highways. Driving on public roads is the reason the state is empowered to regulate your driving, not merely the fact that you are driving a motor vehicle.
True but you can get a DUI on private property if the LEO’s see you ... I live up a private property easement road and a neighbor dumped his ATV while drunk. When I called 911 a cop showed up too and cited him ....
