Come to think of it, I've never heard of carbon driveshafts being used on semis, either...

Regardless, my last statement could be applied to any case where carbon is used successfully in manufacturing, whether it is actually used on trucks or not.

i dont disagree with you digdug. . . carbon fiber is a great material. manufacturers just dont see any point in letting that kind of money go when building those trucks. . .
