Get a little too close behind me & you will see a custom bumper sticker that says
NO, I AM NOT IN A HURRY
On the serious side, no, I am not one of those doing 55 in a 65 zone. I am more likely to be set at around 63/64, the speed the truck gets into & stays in top gear comfortably.
What really pulls my chain are those who are close enough to push but don't use the opportunity to pass when they get it. Then there are the dawdlers who crawl past where there are overtaking lanes holding up everyone else behind them like nobody is there. These poor suckers have to wait till we get to the next passing lane.
I like the Texas habit. When you see it is safe to be passed you drive on the shoulder giving good visibility & they shoot past, always waving thanks as they do so.
