Rapidly spinning wheels MUST have some effect on aerodynamics, since any single point on the wheel will be following a path similar to a ball bouncing forwards, albeit not losing any energy. Believe it or not, when a wheel is rolling, no part of it ever travels backwards. As for the driver or questions of excess speed, I'm willing to guess that no one will be IN the car, it will probably be secured to the device, with the engine and transmission controlled remotely.

Another thing, the wind tunnel is to test aerodynamics, and they have tests for everything else. Probably be a lot cheaper to run through those tests than the treadmill and the car exceed 180.

There are only 3 of these in the world, and this is the bigget in North America. So the ground and the wind can go 180 mph. The queston is, who is crazy enough to drive the car?

The ground will be moving beneath the car at 180mph as the car itself sits essentially still in the atmosphere. Good luck on the aerodynamic tests.

Plus, my understanding of dnyo rollers is that they are usually only in motion on the driven wheels.
