It might work on the bicycle if all the spokes were teardrop shaped in section.

Flattened "aero" spokes are indeed a thing. I guess I shouldn't be surprised that "aero" valve caps have made their way to cars.

I think I'll order 12 and put them in a row over the stubby antenna

I made a wing shaped sleeve for that antenna, but it took a few attempts to get it sturdy enough and even then it lasted just a year.
Also I could not distinguish its effect from my tank log.
