The ones who will probably be affected the most are those who are commuting to and from work. They can afford the $4.00 gas. Those who are unemployed still need to drive, but they will likely find ways to curve their fuel consumption. Maybe people will smarten up and drive in a more reasonable fashion. There is no need to floor it just to get to a red light or a stop sign. This requires logic though, something many American drivers seem to lack.
