There you go, sailing is popular, both recreational and also in sports. The technological developments from the sport do make it into the recreational ships as well.We don't use wind powered ships anymore either, but sailing is popular.
Motorsport should stop trying to be road relevant and the problem goes away.
I think it is great when there is development in sports at high (or sometimes not so high) costs that it trickles down in to everyday, or recreational behaviours. Rear view mirror, active suspension, paddle shifters, use of carbon fibre, aerodynamics, dohc engines, energy recovery, you name it. It is one of the elements I like about the sport.
