You think the auto industry is bad, try the cycling world. If you aren't Trek, Specialized and well thats about it then your designs are either being ripped off or your design IS a rip off.
Most of the carbon in this day and age is manufactured in either Taiwan or China. The Taiwan stuff is very nice quality but it is still easy to buy your own branded "Pinnarello" frame for pennies. Sad part is that the brands don't care. Trek and Specialized are big enough to have their own facility/GIANT where you don't see stolen designs for many years. The smaller companies end up just buying the same **** someone sold four years ago for 1/4 of the price. Screw it! Let them make copies!
