I've suspected the same thing for a while, which is partially why I'm building it in a usable now, but easily modifiable later design. I wanted to taper the sidewalls like in my mock-up picture with wood, but that made my usable space a bit too tight in the rear.

The 'template' is a 3-D structure. It's plan-view taper mimics the roof contour.

I ride one every other day. I sit just behind the articulation, at the bike rack. There are four seats on the turnable (popular with the kids).

A stretched material can still vibrate. I think that's the problem. Maybe a flexible membrane could be structured to absorb turbulence in the boundary layer. I dunno.
