The BOM for a an AM radio is a few dollars only, what's the point of even lobbying? An antenna coaxial and a superheterodyne circuit on the main radio baseband (modern cars all come with a cellular connection) is all you need. You barely need any new parts, the existing components can be modified to support the feature.

It is easier to drop AM radio than suppress the RFI. https://www.nytimes.com/2022/12/10/business/media/am-radio-cars.html https://www.nytimes.com/2022/12/10/business/media/am-radio-c... Technical point, you generally would not be able to recover an AM broadcast signal from a cellular baseband. You might be able to get it from a direct sampling receiver (some RTL-SDRs can do this), but it implies additional band filters and of course an antenna.
