Experience from years of over the road trucking says that no matter what your speed, be it 55, 65, 75, 85, or 95, you always average 55 over the long run. The faster you go, the more often you need to stop.
Just a small example..........I do a 450 mile one way commute to work. I never speed, and I'm often passed by the same vehicle 6 to 7 times, yet we arrive within seconds of each other. The difference, I see no need to stop. They do, and often. I'm sitting back enjoying the drive at 100km/h while they're doing 140-150km/h whiteknuckling it all the way. They don't get there any faster. Why bother?
Also very often, the same ones who fly by me are the ones I laugh at when they're in the ditch buried up to their roof in snow. The unwritten "code of the north" says you always stop for anyone in trouble, but if I see someone who's passed me at ridiculous speeds, unless they are obviously hurt or freezing to death, they can stay right in the ditch where they deserve to be.
There is no need to exceeed a posted limit. Plan your trips to allow sufficient time. Period. Truckers get paid by the mile, private individuals don't. If anything, there should be seperate lanes for trucks, that smaller vehicles are not allowed in, gated or fenced...........and let the trucks go. There's an entirely different scenario happening there..........if a big truck is geared for a certain speed, it actually wastes fuel to go any slower. Example: Let's say the truck is geared to be able to do 80 with a full load. this equates to a certain engine rpm in a certain gear. If it has to slow down, it has to run in a lower gear, possibly even two gears down, at the same engine rpm. Wasting fuel. The big truck may have 13-20 gears to choose from. If it runs in a lower gear, it just runs that much longer to cover the same distance, while burning the same amount of fuel per hour. Yes, wind drag does come into play, but not as much as you would think.
But the small vehicle, if it runs slower, runs at a reduced engine rpm, thus saving fuel. It's a balancing act for sure, every vehicle has its sweet point to run at, but very few small vehicles get their best mileage at high speeds.
I know my F150, at speed limit, gets around 15 imperial MPG. If I were to get up to the speeds you guys are talking about, I'm down into single digit mileage. And our gallon is a quart bigger than yours.
I'm not kidding at all when I say my grain truck that weighs 27,000 pounds empty gets just as good of mileage at speed limit as the Ford does. it will run at 75 mph and do considerably better. But do I need to go that fast? No.........are the speeding tickets worth it? I haven't had one in over 30 years. I like my license!
