A new EMI threat?

Have we got a new EMI issue and threat on our hands?

Electromagnetic interference (EMI) issues have a long history of stirring up troubles and much attention has been devoted to addressing such matters under the watchful eyes of regulatory agencies all over the globe.

However!!! Have we got a new EMI issue and threat on our hands?

The following is an excerpt from a Google search result from “no am radio in electric cars”:

This is alarming indeed. Some auto manufacturers are planning to keep AM radio capability, but are those manufacturers who cannot solve their AM radio EMI problems going to be allowed to market products that will take us back to the middle of the twentieth century?

Back in 1967, I was watching an episode of the “I Spy” television program starring Robert Culp and Bill Cosby. There was going to be one last vignette just after a final commercial when a 1957 Ford station wagon pulled up on the street just outside my window and sat there idling while putting out so much EMI that my television reception was totally disabled.

By the time that station wagon was driven away, the next program had come on and I had completely missed what I had wanted to see.

Are electric vehicles going to bring those kinds of scenarios back again?
