I don't think these CEOs get how actively user-hostile the "wanting to control the whole experience" is. We as users are saying we want to control of our devices, and they are saying "that isn't the experience we want you to have - even if it is the one you want."

I’ve seen those advertised but reviews seem very mixed. At least on the smaller ones that don’t attached with a cord.

The one I got worked, but there was some extra delay of a second or two, and it did not play well with the built-in Bluetooth. If it had been my car, no big deal, but it was my wife's, and she would not just have her phone forget the car's Bluetooth (although the internal implementation is one of those really annoying ones that autoplays the last music source every time you start the car).
