So you probably want to enforce a check on having am radio and that it actually works because young folk won't notice it not working as they won't be using it. This means that the enforcement will likely fall at least partially on the car owner. I wonder how younger folk, who have less financially stability and are not as interested in the radios as the previous gen, will react to this potentially new requirement.

This being the US, I would expect the kind of people that argue against socialised healthcare to also argue against on the basis that each person should be capable of purchasing a $10 am radio receiver and keeping it with themselves, their emergency bag or their car for emergencies without needing the state to play nanny
