How do you get the plastic to deflect more as the speed increases? I’ve thought of a few ideas, but they’re all pretty Rube Goldberg-esque. I'm sure a track-tested solution is better than my idle musings.

But if wildhorsesracing isn't available, and anyone else has some idle musings, please share.

The plastic we use is stiff but flexible to take any abuse that an off-road excursion can produce when racing on a road course. It will automatically deflect based on airpressure built as speed increases. There have also been more deluxe versions that involve gas shocks from a hatch/hood...

Ah, thank you--I had the impression that it opened up in stop and go driving and closed down at constant cruising speeds, which I think would be better for on-road use.
