    Nice article, but:

    I know many have concerns with the radio, but is the above true? Maybe for AM only?

    Alpine has always had terrible AM sections from inception of the company! I was told once that they sacrificed the AM for the sake of a better FM and other components.

    I don't think it's because of the electrical interference from the car because you can shut everything down and the radio will stay on until you remove the key, still without reception. I don't think Tesla installed the FM antenna correctly, or maybe not to Alpine's specs. There's no visible antenna and carbon fiber will block radio signals almost as well as sheet metal. When it went in for service recently they said they were going to "try something" to improve it. I don't know what they did but my car now gets a couple of stations, although with considerable static.

    Haven't tried AM but I can tell you that prior to my recent service where they changed something, I got no FM reception at all. It wasn't just my car. At a recent event all 3 Roadsters with the Alpine unit had the same reception that I did. Nada.

    AM is just the sound of the fluctuations in voltage to the motor. (kind cool actually --for a minute or so) Tesla spec'd no antenna for the car. There is a wire under that dash that is the antenna. I think to say "interference" is not fully correct.

    This has been covered long ago in radio threads.

    "Interference" is completely misleading, as the Roadster does not emit any significant interference. That is giving it a bad rap. Poor antenna performance, possibly due to the CF body and/or placement, is the cause.

    Yeah, it may even strike fears of unruly EMTs into the easily concerned.

    Back in the days of coils and points, the typical car produced so much electrical hash you couldn't watch TV when one pulled into the driveway.
