Automakers want to dump AM radios from new cars
Washington Post reports:
AM radio is being removed from many cars,
potentially ending its century-long love affair with the American automobile
The breakup is entirely one-sided, a move by major automakers to eliminate AM radio from new vehicles because the signal interferes with electrical engines. Station owners, listeners, first-responders and politicians from both major parties are protesting.

How can the AM radio signal interfere with electrical engines? The "signal" is in the air, all around us. It is up to the electrical engines to shield from AM in the air.
I think what they might actually mean is that the electrical engines generate signals that interfere with the radios - because sometimes stray signals from regular IC engines will mess up the AM signal.
