I honestly can't remember when I listened to an AM station, and also if I wanted to listen to an AM station these days I would listen to it via an app that streams AM stations, not the actual radio itself

End of a love affair: AM radio is being removed from many cars

After a century-long romance, the car and AM radio are breaking up, leaving conservative talk shows, programs aimed at immigrants and religious stations wondering how they'll connect with listeners.

@scalzi AM is used quite heavily for weather and road information broadcasts and is important in the western states like Montana. FM doesn’t travel as far in the mountains as AM.

I live in a mountainous region, and most FM stations worth listening to have translator/repeater stations to handle the geography.

That said, my newest car came with SiriusXM satellite radio, for which I pay about $8 per month. No commercials except them promoting their other channels. Uninterrupted listening, occasional drop-outs when a mountain blocks the line of sight to the satellites.
