No one else wants to touch the subject so I will. Several years ago when there was a "gas shortage" the decision was made to limit the maximum speed nationwide to 55 mph. This saved gas and lives. Now we have gas gosling MPVs, fewer car pools, and fast speed limits. No one wants to make the decision to slow down to a more gas conserving speed. Instead other methods are implemented such as closing schools and dipping into the war reserve so that the voting public can maintain the style of driving they are accustomed to. It would be a very unpopular decision and political suicide for anyone to say, Slow down!
