Just so there is no mistake, my speeds are determined by two things. First, by driving at 63 I can let the cruise handle all the driving because I rarely need a lane change or have to brake for slower traffic. This thing is a recreational vehicle and when I am in it I want to relax.

Secondly, the stopping distance at a lower speed is significantly shorter than at a higher speed. It may not seem like much, but the small 10% speed change to bring me up to 70 MPH increases my stopping distance by about 20%. Just to put this in perspective, the average car can stop in about 130 feet from 60 MPH. A Prevost towing a car may take as much as 300 feet from the same speed. That is one of the reasons why I get really concerned when I see a bus or truck trying to intimidate a car by tailgating.
