When you start out on a four plus hour trip back home or a seven hour turn via, with a ten minute buffer, yes it does make a difference. Every second counts, from filling out logs to amount of time to hook and un-hook. Getting stuck behind a slow mover can make a difference between burning up that sweet sixteen and or being picked up. As we know, having to be picked up seems to always perturb the brass at your barn. This is not Con-Way anymore, profit is what makes this company turn. In order to make profit, having line drivers out fourteen hours all day, every day will cut in on profit. UPS feeders zip pass us with their two light pups all day. I don't even remember when was the last time I seen one of them wrecked. FedEx Ground guys fly by us at seventy plus, with a set all the time. What differentiates those drivers from us. Are we not professionals? Having to constantly do three county passes because other drivers do not have the courtesy to let you pass (looking at you OD with your fancy sixty four mile per hour tractors), causes severe traffic jams that infuriate the drivers around you. Which could possibly end with road rage. Imagine all he traffic tie ups if this speed limiter regulation pass. There will be some road raging four wheelers out here (not like they are not here already). Just look what happens now when someone is slow rolling in the passing lane, it will only get worse. If you are concerned with the regulation, write a letter to your senator and congressman.
