There’s nothing wrong with slow and steady, as far as it goes, but I think it is a bit subjective. I’m not too keen on the traffic in Florida or California, but if you were pulling heavy in an old truck on the interstate in Kansas, and going 20 under, you’d be causing lots of congestion, as much traffic as there is on the interstate here.
Few people in Kansas drive slow, there’s lots of distance between places of even the smallest significance, and driving isn’t particularly productive, we’ve got stuff to do. There’s another Kansan here from the western part of the state who probably has a similar opinion about this. There’s few short distances around here, and plenty of long ones. Just drove 620 miles today in fact. It’s not productive, but necessary. Driving 50-55 would have taken all day, driving 75-80 just took most, and gave me enough time to accomplish everything else I had to do today, and still make it home in time to go 200 miles in the other direction tomorrow morning, to return the night of the 4th. Not a personal trip. Driving below 40 mph on the interstate is illegal in Kansas, which, obviously, that is very slow, except in mountainous regions. But if you’re only going 55 in your NA 7.3 with 18k lbs behind you, you might only be going 40 at the top of a hill. The whole speed thing seems relative and subjective to circumstance. Just my 2 cents, the elaborate kind with the heads of wheat on the back side of the coin. Kansas out.
