One of my coworkers and I both live around the same area. I commute to work via bus, he drives (occasionally we carpool, but our schedules are different most days). He doesn't understand why I would take the bus when it's a fifty-minute ride via bus and a twenty-five-minute ride by car.

However, I can use the time on the bus to catch up on email and news (I'm paid by the hour, so no point in working on the bus if I'm going to put in an 8-hour day anyway), or even doze off slightly. By contrast, when you're driving, your attention has to be entirely focused on the freeway. So while he has 50 minutes of being locked up driving, I have 100 minutes of time to relax.
