Passing the Time While Driving [POLL]

Since most of us live in Amarillo we don't have a huge commute to work, but if you live in some of the surrounding towns and commute to Amarillo, you have to make a long drive daily.  So not matter how long you are in the car, how do you pass the time when you are driving.

I'll admit I'm a singer.  I love to crank up the radio and jam!  Do I care who is watching?  Not usually, but hey if I get caught, I get caught.
