"Indeed. There are many such highly-specialized contrivances in sports
and
competitions these days. Take for example the trials bikes--not much
good
for motocross or trail riding, but they do what they do better than any
other motorcycle. Same with sub-specialized ski boats, those radical
multihulls built only to break the world sailing speed record, Burt
Rutan's
various aircraft designed with a sole purpose in mind, F1 cars, and so
on,
ad infinitum. It's hard to be critical of such creations as a lot of
technological fallout makes its way to the things we buy and use daily.
