Think more broadly - lots of the world is shutting down AM - but the USA is an outlier, because AM's an advantage, geographically, and very little of our FM stations (or TV for that matter) are state-owned (unlike lots of the world) - so the free marked prevails. There may also be an interference aspect of EV motors in the AM signal - rendering them useless anyway.

sorta, but its a geopolitical catch....as I said it takes very few volts - and thereby watts to cover the US - especially at night. There are numerous reports of mild 20w linear'd CB radios going coast to coast. Who here has not listened to the 'FAN' (WFAN NY) from anywhere in the US, and never set foot in NY?
In europe any idiot with a 50watt transmitter can cover everything and the people in charge are not so much into that.
Just the other night I fired up the S350 Grundig and DX'd using just the 1M antenna - even SW1-2-3 were mostly devoid of stations. lots of carrier signals, but those are imbedded with digital data or encoded digital voice - to keep you out.
btw- ye olde fashioned points ignition did a fair number on AM reception years before EVs. Small sources of interference were easy to choke off, not when every powered item in the car is a source.
AM radio is going the way of CD players in cars - those who do, are far outnumbered by those who do not - same as ordering AC or stick shifts or manual windows...its far easier and cheaper to build to an exact set of standards instead of 'options'
