I think the GP's point still applies: if you're spending that much time in your car every day and it's not your job, you're doing it wrong. I have a 15 minute commute each way and would move if it ever went over 30 minutes. There are better things to do with your time than having your butt heated while listening to traffic reports for an hour.
If you commute for 10 hours a week, you're looking at 500 hours in a year, assuming a 2 week vacation. That's over twelve 40-hour weeks of commuting. You could spend that time at work earning extra money, or spend it on hobbies or sports, or with your loved ones. I don't know anyone who would pick sitting in a car, no matter how comfortable, over at least one of those options.
