Just give me a standard steel or aluminum driveshaft and keep the exotic materials.
Good point... I don't really care about the carbon driveshaft, but it will be very disappointing if BMW skips the CF roof; this is the place to shed weight, and this car (more than any other in their lineup) is the one to focus on weight.
