Unfortunately, these are bicycles, not airplanes, and definitely not fish. How much of the cyclist's stability depends on airflow across the tires in a crosswind?
I once heard it stated that 95% performance isn't all that expensive - with ability and effort you can omit the exotic and run with all but the top 5% in everyday life.
It's that top 5% that gets unbelievably hard and expensive. I think this is a "top 5%" idea - maybe a marginal improvement. Could you get the same benefit by shaving your legs, losing a few pounds or carb loading? Probably.
Oh well, your yuppie friends will be impressed anyway.
I darned-near crashed one day at 30+ MPH due to a crosswind-induced front-wheel flutter.
Remmeber that in 1989 Greg LeMond won the Tour de France by a margin of 8 seconds out of ~300000 seconds.
