Since the iPhone has replaced my Walkman, my friends have replaced the DJs, and the ability to listen to whatever I want at any given moment kicked out radio stations' playlists, I would say it's time to turnofftheradio for good.
The new body monitors could, if a driving hazard appeared imminent, trigger the car's safety systems to tap the brakes, turnoff a radio, block a cellphone from ringing or take other actions.
