<p>Back in 1974, President Richard Nixon put in the National Speed Limit of 55 mph, according to the National Safety Council, this measure helped the number of traffic fatalities decrease. But Sammy Hagar wrote a whole song about how he couldn't drive 55. But we're guessing he's happy now as in most states the average speed limit on highways is 65, and in some places even higher.<br></p>
