Thanks for providing the source.

I'll just note that again, my hypothesis and the actual way it works are very similar to each other, and both are very dissimilar to the suction cap analogy. Suction cap works by utilizing atmospheric pressure, this utilizes moving a large amount of air in the direction opposite to the road. The only difference is that it's taking the air from below instead of pushing from above. I imagine that is the case to utilize the same outlets that are used for lifting the car.
