If cars were licensed like enterprise software, they would detect how many seats were in use for the trip, and we'd have to pay per seat.

I've had a satellite radio button in my cars for years, but never subscribed. The hardware is there to receive the satellite radio, so it's a content (and software) license I'm missing. Do people not complain about that because satellite radio is not seen as a feature intrinsic to the car?
