"shielding" kind of glosses over that the components in EVs tend to emit more electromagnetic interference (EMI). This article seems to be a nice overview of the issue: https://www.radioworld.com/columns-and-views/guest-commentaries/control-emi-dont-dump-am-receivers https://www.radioworld.com/columns-and-views/guest-commentar... I guess implementing a receiver that is isolated from the interference can cost more than a few cents though (because it's the whole signal path). AM HD is digital and much less impacted.
