Years ago I met someone who was a high up / owner of a EM testing facility. He took me of a tour of his facility, and we went into chambers that were radio and acoustic silent. I then asked, "uhm, normally electronics aren't this big, what are you testing in these?" "Oh, we test cars for EM in here" "Uhm, those doors seem a little small for a car. Are you testing the Tesla?" (At the time, the very first Tesla Roadster wasn't on the market, but it was probably the only car I could think of that would fit through the doors.) He then lowered his voice and got very cagey. "We don't talk about our customers" was his response. A few minutes later the tour ended in his office. He asked me to walk around his desk. There were pictures of him all over the Tesla Roadster, clearly excited to have it grace his presence. The funniest thing: He wasn't allowed to drive the Roader. (Conversation is paraphrased) --- Ironically, I wonder how easy/hard it will be to have a functional AM radio in an electric car. Is it one of those things where all you need to do is twist the right arm, or is it something that's practically impossible?
