The longer the trip, the more savings there are to be had from speeding up. For example, a friend of mine and I were in a rush because we had an orchestra concert that ended at 10PM, a 2 hour drive (normal speed), and she had work at 6:30AM the next morning. By driving 90MPH, she cut 30 minutes off the 120-ish mile trip, but that's a longer drive than most commutes
and significantly higher than "just 5MPH over."
When I drive 30 miles north to see friends, I've discovered the time difference between 55 and 70 is not worth it.
