$11.88*5days=$59.40 cents per week
$59.40per week *52 weeks=$3088.80per year.

This type of thing was popping up all the time when CFI went to 65mph. If you work exactly 11 hours a day, all driving is done in areas with speed limits higher than 62mph, traffic would have never been moving slower than 62mph, you start at top speed and stop instantly at the end of the day, and your company's available freight would use exactly the number of driving hours available under the law to cover the dispatched miles, it might add up to that.

In reality, you don't get a 682 mile per day dispatch, along with a message saying that you would have gotten a 715 mile per day dispatch if your truck were faster. We got a penny raise (along with a 5mph reduction) to start this year. I heard at least a thousand times that the raise was really a pay cut and all that jazz. It's simply not true.

Thats kind of the point that I was arguing. That a speed reduction needs to come with a pay increase. The loss of income from a speed reduction would not be that much, but it would still be lost.

Well, speaking simply for myself, the reduction in speed has not translated to a drop in miles. Since we're paid by the mile, only a drop in paid miles could equate to a pay cut. All that hourly stuff is fun to calculate, but we don't get paid by the hour. The cpm raise has translated directly to a raise in monthly pay for me, as my miles have been at or slightly above last year's level, even with the slower truck. We dropped 5mph, as opposed to 3mph, in the process.

My point is simply that you can have a 100mph truck, but you might still only get 2,000 miles next week while a guy with a 60mph truck may get 3,000. The available freight doesn't generally match up exactly with your hours available.

Company expert or not it is like Fozzy said "physics do not apply" Quoting from http://en.wikipedia.org/wiki/Drag_(physics)
Note that the power needed to push an object through a fluid increases as the cube of the velocity. A car cruising on a highway at 50 mph (80 km/h) may require only 10 horsepower (7.5 kW) to overcome air drag, but that same car at 100 mph (160 km/h) requires 80 hp (60 kW). With a doubling of speed the drag (force) quadruples per the formula. Exerting four times the force over a fixed distance produces four times as much work. At twice the speed the work (resulting in displacement over a fixed distance) is done twice as fast. Since power is the rate of doing work, four times the work done in half the time requires eight times the power.

I've been in this same discussion hundreds of times over the years and it still comes down to the same thing as telling someone thoroughly convinced that there is a Santa Claus who lives in the north pole. High speeds in trucks have become like a god of sorts.. and just like the extremists of one of them, if you dare to question it with fact... the zealots start to have some melt downs and tantrums. :lol:

Sure but here's the problem:

What type of testing did you do? If it wasn't on flat plains, then it's not worthwhile.

If you're on a perfectly flat plain, every time you bump up your speed, the instant readout drops.

Doing tank to tank comparisons may not work, because you're not eliminating variables unless you're doing the exact same run with the exact same trailer on the exact same route.

Like the other poster said, drag increases to a square of speed. There's no way a small difference in engine RPM's can make up for this.

I've done tons of testing on I-29 north of fargo to the border. I've come to the solid conclusion, based on facts, that speed matters 100X more then engine rpms. "spec the truck to go fast" is utter horseshit, it does not change the huge horsepower requirement to go that fast.

I hope you are NOT telling me there isn't a Santa Claus who lives in the north pole!!

I do agreed about the zealots. Some where along the way they either don't know or have forgot the rules of physics.

I agree, there is no Santa Claus that lives in the north pole. He saw on the news that the ice caps were melting so he built a large yacht and spends most of his days in the Caribbean now. He knew that if he saw it on CNN, it must be fact so he got out while the gettin was good.

Funny story: One of my friends' daughter found out a few years ago that there was no Santa and started crying. He asked her why she was crying and she told him that if there was no Santa then she wouldn't be getting any more presents for Christmas. He told her, you dummy, who do you think has been giving you these presents all along?

It is NOT cheaper labor. It would take the driver longer to do the route, but it would NOT result in cheaper labor!

If you have to pay a driver a certain rate per mile, and the amount of miles in the route are the same, you are paying the EXACT SAME AMOUNT!!!

a 500 mile trip, paying $.35 a mile to the driver will pay the same, whether it takes 8 hours, 10 hours, or for that matter 30 hours!

Quit bitching for the sake of bitching! Find something REAL to complain about or SHUT UP!

Man your intelligent. If takes longer to complete a task and your compensated the same amount, you are working for less.

Your the type of person companies are looking for to sign a lease on agreement.
