530 Hours in the Car Each Year!

In this week's This Week in Tech podcast there was mention that according to a University of Texas report, the average commuter spends 530 hours a year in the car. I've been looking for a reference to this one and haven't found it yet. If anyone reading this does find it, please pass it along to me. That aside, this is a really good stat for driving home, pardon the pun, the mobile computing point that we all could be listening and learning more while in the car.
