Well I used to have a 35 mile round trip bike commute that I never minded too much. That would mean that if I had to drive a car to get to job A then it would have to be in the area of 50 miles or so round trip AND not link to public transit in anyway to make it bike able. So that would mean that I would be looking at loosing about 1-2 hours a day by having to drive in rush hour traffic which is also very dangerous in terms of car accidents, breathing in the stop and go traffic, stress, and not being able to cycle as much as I do. I would think that Job A would have to pay me at least twice as much as Job B, even then I would have to think about it.... I would consider moving closer to Job A so I could bike but then I would be somewhere that apparently has no mass transit which would be lame... Job B for me!
