That was a good read.

Put air deflectors in front of your tires. Make them out of conveyor belt. Also make a conveyor belt air dam. You can drag it offroad and you won’t tear it up, but it will improve your fuel economy and improve your onroad handling.
Not only for off-road, but also for highway speeds, cinch that air dam down really tight.



This example is inflexible, for a different environment; but look at the dozen screws (under pan washers) holding that on. Granted they are at higher speeds, but (seriously) it's a Beetle—how fast could it go?

They said they had to take it off to get the car on a trailer.

If the conveyor belting is held with L-brackets, make each one a little quarter-elliptic spring, stiff enough to resist the air at speed, but flexible to take abuse off-road.
