If we have a catastrophic natural disaster in the US, we won't run into this problem
That doesn't work because we have catastrophic artificial problems.

No, the wheels drive the propeller. The wind still pushes against the propeller, and that's what pushes the car forward, but some of the energy is taken back from the wheels to turn the propeller and blow air backwards. The result is an addition to the wind speed. Alternatively, you can think of the propeller as part of the car that is going enough slower than the car that the wind can still push on it even if the car is going faster than the wind.
One small step for man, one giant stumble for mankind.
