In a 1976 Corvette you can turn the radio off after turning the ignition key off.
I think most, if not all newer vehicles being electronic will not allow this to happen.
The thing I don't like is my radio doesn't work with the key in the ACC position. If I want to sit in the parking lot while my wife shops and listen to the radio I have to put the key in the run position. That will run the battery down for sure because everything is hot including the ignition coil.
