A flat cap for speed limit days and a baseball cap turned round when you accellerate away from a Bmw driver on your tail seems a good compramise to me.

Surely it would be the crass BMW driver that was wearing the baseball cap? Oh dear! Now that I think of it the Aero is a BMW. (well engine, gearbox, ECU, etc)
PS. I don't feel at all stigmatised. Folliclly challenged, yes, but stigmatised, no. I need something to protect my sun damaged scalp so I always were a hat when out in the sun.
