That driver you’re passing that’s going under 65 is probably me! lol I can’t afford a ticket, number one. Two, my car gets better gas mileage when set on cruise at 60. Three, I’m never in so much of a hurry that I need to speed. And, yes, I pass cops. If they’re not doing the speed limit, I am not intimidated as other drivers seem to be that I see all the time who follow behind behind a cop doing 45 in a 50, or 25 in a 30. :~)
My car definitely gets better gas mileage going slower, or when my wife is driving. It also gets better mileage if I tuck in behind a fast-moving truck.
In fact, with the need for high air conditioning on our trip to Orlando, along with my aggresive driving trying to make the journey quickly enough to spend a good amount of time at a theme park on Saturday, I barely hit 40 mpg.
