Lowering the speed limit is a good move period. Yes people speed all the time, and yes the will keep doing it. But they will only do it to a certain point. 20 MPH over is reckless driving, so you see alot of people going 80-85 where the speed limit is 70. How many go whizzing by at 120? Not many because there is a point where it is enforced and quite harshly. So if you lower it to 55 or lets say 60...people may still speed but they will go maybe 70 instead of 80 and it will still reduce fuel comsumption. Saying that drilling for more domestic oil wont lower prices is ignorant. Alot of flucuation in the market is due to speculation. 2 weeks ago crude prices had dropped $6 dollars then Iran tested new rockets. Increasing speculation that war with Iran could happen. Crude prices went right back up. About a week ago GWB removed the executive ban on drilling and crude oil prices have dropped 16 dollars a barrel since. Just the feeling that there will be more future oil supplies is enough to drop prices. It may take 5-10 years to drill but if the market knows more oil is coming they dont have to increase prices to slow demand. If you want to speed, do it. But saying that slowing down an entire nation (the nation with more vehicles than any at that) of vehicles wont help fuel prices, is...well...retarded to put it bluntly.
