Why Are Some Automakers Ditching AM Radio? Because they suck!

If you think EV cars are bad, try diesel locomotives, or any metro rail vehicle that runs off of the 600VDC, 800A, third rail. Those blow away from DC to light of RFI. Oh yeah... Not just them, but ever hear why smart phones don't offer OTA AM, but just FM? Same deal, RFI spectrum-wide. BTW, as if EV didn't cost too much as it is, but if they were to implement RF filtering and shielding, that would just raise-up the cost of them even more so. [www.radioworld.com]
BTW, SWL'ing 1st lead me to this.
