In the winter, when its nasty out or my when driveway is especially slippery I'll shut the radio or my audio book off so I can concentrate on just driving and figuring out how to get up the hill...
For commuting I might turn off the radio for the couple interesting parts where I can have some fun, but most of the time its on.
