Oh, it may well not work in dirt. I suggest using tarmac or a well treated salt pan.

The body is a non-dimpled golf ball? Just like an aircraft hull?
Planes don't fly and gliders drop like bricks... /s
Viscous shear etc. is present but at these speeds it is not as dominant as you pretend. It isn't even prohibitive at aircraft speeds, obviously.
This is more of a physics event than an aerodynamical one.

The blue wheeled car is just to demonstrate how it is possible to move faster than the difference in speed between the two media touching it.
The Blackbird is another example, but the execution is different even though the principle is the same.

It seems you still don't get that the propeller is moving the air slower than the car moves itself, and it is absolutely essential to grasp just that to understand how it works.

You are presented with something you really don't want to believe.
You better make sure you are not a victim of cognitive dissonance. That turns an enlightening challenge into a horrible one.

For confirmation go to people just like you.
For education go to people unlike yourself.
