> EMI is a real issue

To the point they are wanting to eliminate AM radio because they've gotten to the point that the uncontrollable EMI makes AM "unlistenable". So move the goal posts, and make AM radio out-of-fashion and get rid of it rather than solving the EMI issues.

1) I don't think you'll ever be able to make an electric vehicle electrically quiet enough to make AM work nicely and if you somehow did between the shielding and all the balancing currents there's no way it would be efficient. I like AM radio but these two things are probably never going to be compatible.

2) WiFi really isn't as reliable as a cable. There are all kinds of things internal and external that could cause an outage. Why bother with that when you can just run maybe a dollar of copper to the ECU?
