This is already being done by moet major brands these days. They can only withhold luxury features like heated seating for now, but who knows when they take away basic features such as radio, replace it with a Spotify app, and demand a special subscription to listen tk music in your car.
I was trying to look up a Tesla special case (where upgrading the infotainment unit removes the radio unless an additional $500 upgrade is purchased) and learned that several EV manufacturers have already removed AM radio because electric motors interfere with that frequency range.
