It tends to take me about 10 minutes to drive to or from work. Fifteen if traffic is heavy. I wouldn't be willing to work farther away from where I live. I got an offer for a job that pays $1/hr more than what I have now, but it's on the other side of the city and I don't do rush hour San Antonio traffic unless I just have to.
Funny thing is, I have actually applied for a job as a WIC counselor that would entail driving all day long to folks' houses. I will reapply as soon as I can.

I'd love to have that particular job.
DH drives all day long; he's a drain tech for Roto Rooter. Since he has to drive a van, he uses at least $100/wk for gasoline. He travels not just in the city but the whole county and several surrounding counties. He's had a couple of jobs that were 2 hours one way to get there (and then one day he had 5 jobs within about 10 blocks of each other).
I have a '95 Ford Taurus station wagon, & Rob has an '01 Chevy whatevertheheck cargo van. I usually spend about $20 on gas a week, if that. I love my mileage & my cruise control.
