This is the most important use of AM radio in cars: https://en.wikipedia.org/wiki/Travelers%27_information_stati...
I found that AM radio had so much interference 20 years ago listening to Radio Disney that I gave up. (oh god. That might be closer to 30yrs now)
Dipping my toes into software defined radios (RTL-SDR, and a HackRF), I found AM to be incoherent in my area.
So, what exactly is there to save? It's obvious there's an agenda- FCC already has enough latitude to allow low power FM broadcasts to replace AM ones without external involvement.
I think you succeeded in motivating for the opposite of what you intended...
You can get home receivers that monitor NOAA radio for emergency alerts tones and will automatically switch on in a disaster.
It's a great feature, every home should have one.
