[quote=Anonymous]The other part of the why is that people usually optimize for their personal utility, finding the best combination of low cost and low time commitment. Since most of us already have the "sunk cost" of car ownership, we only think about the cost of driving in terms of the additional cost per mile of gas and maybe wear and tear if the commute is really long. Some people may take into account the cost of using a parking garage at work if they must pay that out of pocket. Unless a transit commute feels like it consistently takes less time and mental effort (that's where reliability is important) and costs a similar or lesser amount, drivers are reluctant to leave their cars. Widening freeways reduces the perceived cost of driving. Drivers do not recalculate that cost and compare it to alternatives often. As well, they may have other factors, like picking up children from school or daycare or errands that may make using alternative commuting options difficult once they have selected a job and house location.
