> AM radios in cars only cover the small intersection of people who don't already have an emergency kit containing an AM radio, but do happen to be in a working vehicle during a disaster.

I feel like the number of people with a working vehicle is much, MUCH larger than the number of people with "an emergency kit containing an AM radio."

The main point being that, if you happen to be traveling at the time in a potential emergency situation (either because bad luck or actively trying to evacuate), you can use the AM radio in the car to receive news and important information.

Just put the radio in the car where it's most likely to be used when needed.

> The electronics that drive such powerful motors produce HUGE quantities of RFI

The electronics that drive such powerful motors are inside thick, cast aluminum housings, as are the motors themselves, and those two things are usually bolted directly to each other to form one massive lump. I don't think you appreciate how much RF shielding goes into all that already because, y'know, there are a lot of other electronics in the vehicle that might get fucked up by it. The $5 worth of metal" would be the shielding can around the radio itself, not the HV inverter circuitry that is already encased.

The "Electric vehicle electronics interfere with the AM radio signals" argument is complete horseshit. The AM radio in my 2020 Kona EV often works better than the FM radio for some reason. It's not an especially expensive vehicle so the cost of making it work certainly isn't a reason to not do it.

I wouldn't be surprised if the all-in COST of making an AM radio work decently in an EV was at least into the hundreds of dollars.

I doubt this very, very heavily. If it were so they would have told us so already as their excuse. These days the typical radio antenna is an amplified module mounted to the roof, this is now cheap and it gives better reception without the sticking-up aerial or with just a short one.
