QotD: Passing The Drive Time

When driving alone, what do you do?  Sing along to the radio?  Think about your day?  Something else?

I never drive alone in Indonesia. In fact, I never drive in Jakarta. My parents never allow me, because Jakarta's traffic is the worst.
But I used to drive back when I was in the US. Specifically, when I was in Southern California, where my parents bought me my first car (because it was - and still is - impossible to move around SoCal without having a car!). Public transportation is not so good, especially because there's no subway. Well, SoCal is so big, that a car is the primary means of transportation. When I was in college at Penn State, I used the university bus (the Blue & White Loop buses) to move around the campus buildings, and the public bus to go to the mall & beyond Penn State. Also, some of my friends had a car of their own, so they picked me up whenever we were going out. State College is a small town, so I didn't need a car there.

Anyway, whenever I drove by myself in SoCal, I usually listened to my CDs (rarely the radio, because I only listened to smooth jazz radio & there was none in Orange County area, I think). I never sang along if I was alone. I find it weird to do so if there's no one near me to hear me.
Sometimes I called a friend & talked, just to kill the time. Sometimes I had random thoughts, my mind just went rambling around.
The roads in the US are very smooth, they made me enjoy the drive. It's the most essential part, because I actually don't like driving that much.
