You're right. I was using
5 year old data. The US needs to achieve something like a 47 mpg average for its automobile fleet to become energy independent. I just hate to see people pissing away our independence to gain a few minutes in a day. But that's my hangup.
As for going the limit, it's a
maximum limit. A single hypermiler doesn't slow traffic any more than any slow moving truck out there, and there are plenty of those. FWIW, most traffic is already illegally exceeding the limit, and should be slowed down - if not by hypermilers, then by law enforcement. They don't have a
right to speed.
