That is why.
No it doesn't, you can spend $5000 a day in a wind tunnel.
you should read about David Millar's work in the wind tunnel, they spent tens of thousands getting him to optimize his position, but this actually slowed him down on the road. Once he dropped his wind tunnel position and went back to his old position, he won his next TT. Wind tunnels assume that the most aerodynamic position is all that needs to be optimized, but this ignores the mechanics of a rider.
Seriously, unless you are entering the Pro Tour and are optimizing to win a grand tour, wind tunnels will not make you any faster.
