Could driverless cars affect radio listenership?

I'm sure that radio listenership has gone down dramatically since the 1940s when it was originally introduced and one of the few media options in the home. No TV, definitely no internet and streaming, just books, newspapers, magazines, the wireless and having guests over. There weren't even very many channels in each language to choose from. So since we have more choice, radio is not of primary concern. In fact, not many people I know listen to radio in the car anyway. They put on an audiotape (storytape), play some music, or have nothing, because the adverts on radio are so annoying. A true driverless car would make you like a passenger. (At the moment you're still obliged to keep an eye on the road, in order to make sure the technology doesn't miscalculate). Passengers on the train read books, play games on their phones, etc - I don't know how many listen to the radio
