I don't usually drive that fast but was recently passing in a 75 MPH zone when I found out that there's a 96 MPH governor. I assume everyone else has this? It is removable or adjustable? FORScan perhaps? 2018 F-250
There are reasons for the governor. Usually, there are two big reasons.
First, the tires are not rated for speeds above this. They can go faster than the rated speed, but the chances of one blowing up when above the rated speed goes up quite a bit. Second, the driveshaft has a critical speed. If you exceed this speed the driveshaft can fail. Been there, done that, and pole vaulted over my own driveshaft once when I exceeded the critical speed. That was 16 years ago, and I still remember the feeling when I exceeded the speed. The truck shook hard and I immediately stood on the brakes, but it wasn't in time. The driveshaft came apart near the front and dug into the roadway. The rear of the truck vaulted over it. I'm amazed I didn't lose control.
I'm not telling you not to do this but helping you to understand why it's there.
Wow, I knew tires have speed ratings but never heard about the drive shaft part. Good thing you only came away with a crazy story... that and maybe a few auto repairs

Pretty sure you can turn it off. Otherwise Boeing 737's would land on me as I'm running away down the runway in my work truck. (2015 F350 though)
My bike is unlimited. It just turns off the speedometer at 186ish, if you have the ***** to look at it.
If a 737 is chasing you down a runway, the local controller screwed up or you had a runway incursion. A 737’s nominal landing speed, depending on configuration, is approx 135 knots or 155 MPH. Your work trucks goes faster then that?? Do you use the high-speed to turn off the runway?
A bit. I'm on the part of the runway they ain't using at the moment. But that traffic controller is anxiously waiting for me to get off the other runway so he can use it again. And trucks are slow.
I did get a bit of a stern talking to when they said "keep up" and i was stuck in a slow POS chevy Express van. We do go about 120. Those pathetic vans don't.

Sounds like a Hayabusa.
The wife and I have clocked a lot of miles in remote locations 2 up on a BMW R1200 GS LC. Cruising a very lonely, twisty 2 lane in Eastern Oregon once she tapped me on the shoulder and asked through our headsets "How fast are we going?"
"Is there a problem?" I replied.
"It feels like we are crawling!" she said.
I had the cruise control set at 85. We were topping 105-110 passing. I am old enough and my testosterone level is now low enough that I have little interest in speeds above this.
I am very selective about where we hit those speeds on county and state highways and the wife is an excellent pillion rider helping to watch for deer and other obstructions.
Amazing to me is how we can ride a bike or drive a truck for hours on end in absolute comfort and relative safety today.
I have not had my '17 6.7 out yet to test top speed but on dry lake beds my '02 7.3 rev limited at 94 mph. I also understand tires are the primary limiting factor.
In addition to the other factors mentioned above I once read a theory that engine braking a loaded diesel down from high rpm can cause damage but I have never been able to verify that theory.
