Cars are already heavily regulated. The minimum-legal car may not be comfortable and may not be pretty, but it&#x27;ll be pretty darned safe and be decently efficient (considering the amount of material it is hauling around to be that safe). You can&#x27;t advertise a death trap because it&#x27;s already illegal to sell one. It&#x27;s a poor comparison to the medical world where you can not help but do dangerous things to solve even more dangerous problems.
