Higher gas prices should be a good thing, not because they "hurt cagers," but because they will change behavior. For example, people will decide that they can't afford to live far from work, so they will make adjustments in their choices about where to live and work. People will decide that they can't afford vehicles with poor fuel economy, so they will make adjustments in their choices about transportation. Those are desirable outcomes, not just for cyclists, but for all of soociety.
Of course, there are also undesirable outcomes, as Rev. Chuck has pointed out. Food prices will be affected, which will lead to market pressures that encourage locally produced food and discourage distantly grown food. That is a a desirable outcome for all of society. Higher fuel prices will hit the poor and elderly harder than any other segment of society. We need to figure out what to do about that-- but keeping fuel prices low isn't the solution.
