Sometimes an hour of time is easily worth $7.38. 3 vs 4 hours for a road trip is significant. That could easily be the difference between getting home safely and dozing off and driving into oncoming traffic.

I think the real lesson here is that you can take hypermiling too far. I always like to point out that saving a little fuel not worth aggravating hundreds of fellow drivers by being in their way.
