So the airflow under the car is different in the wind tunnel vs on the road.
To make that less confusing: In real life, the air does not move relative to the road. In the wind tunnel, it does.
When you model aircraft, the "road not moving" problem does not exist.

so what your saying is I need to build a big treadmill in my wind tunnel... ill get right on that
