I really don't think #1 should be in there, but its just my opinion.
First of all, 100% of us will answer yes to it. Second, I consider it a bad habit on highways and secondary roads if I'm not driving within the "80th percentile" of all drivers (which has proven to be the safe speed range), which in almost all cases means traveling in excess of the posted limit, like everyone else. With speed limits sometimes lower than back when cars had drum brakes, bias ply tires and no ALB (before the "magic" overnight speed limit reductions when conversion to metric occurred, and other later arbitrary speed zone reductions), I only contain speed enough to avoid the money grabs that are going on.
