A 55mph speed limit would just be retarted. I don't see that their would be much of a difference in gas milage between a 55mph and a 70mph highway speed. If they really want to save money on gas, do something about all the people who dirve trucks and SUV's that don't need them. I'm tired of seeing people rolling around in Cadillacs Escalades because of the status it brings them and not becuase they need the added power and towing ability... friggin soccer moms need to go back to their vans... and all those raised mud-bogging trucks need to go as well. They waiste far more gas than a 55mph speed limit would save. But then again, it would be a hard law to enforce.
Vash- I agree with you. It bugs me when people only point to the top and blame them for all the problems, when it takes several people to make the decisions.
