I have driven a lot of miles. And if I needed to my truck would stroll. (once hit reset on GPS at Iowa/Neb. line. Next reset at CO. line. All the way across the state, average speed, 76 MPH. Yes I was scolded by safety dept)
But most times I would run 62, unless that was higher than the speed limit.
And for everybody talking about how a vehicle rolling 20 MPH below limit, in the right lane of a 4 lane divided highway? Are you saying you drive with your head so far up your rectum that you can't miss a parked car while driving 20 MPH? And calling somebody else a hazard?
