Re: Gridlock is a fallacy
How does the system then account for externalities like job crunches and housing shortages that could prevent people from having alternatives when the comfort zone is breached. In a job crunch, one may not be willing to switch jobs since they don't want to lose their job in hand. In a housing shortage, the long commute may be the only one available or affordable, meaning the price to move is too high or it simply isn't an option. And since people value face time, telecommuting may not be in the cards, either. And if fuel prices rise again, the cost of the commute may eat into the household budget, reducing commuting tolerance.
So the worst-case scenario is one where commuters are in an unacceptable but unavoidable situation.
