From Wikipedia, about the last National speed limit:The law was widely disregarded by motorists. Most states subversively opposed the law, ranging from proposing deals for exemption from it to minimizing speeding penalties.
This cap was intended to reduce gasoline consumption by 2.2% in response to the 1973 oil crisis. However, net fuel savings were calculated by the United States Department of Transportation at 1%, and independent studies found savings as low as half of one percent.
Apparently there are differences of opinion about how effective it would be, And the cost isn't just the price of some large "65" decals, it's the cost of all the wasted time resulting from driving slower than necessary. But as long as we are talking about laws preventing me from doing things I want to do, how about a law preventing others from driving SUVs, or better yet, how about a law preventing trucks from using the left lane?
