Metal Replacement Gains Velocity in Automotive

I or one am not looking forward to the day that I have to try and pull my fully loaded 12,000# flatbed trailer with my brand new all composite carbon fiber CAFE standards compliant 3/4 ton rated truck that just tips the scales at 1300# yet for some reason still only gets 7 MPG unloaded.

Just because they can make a vehicle lighter does not necessarily make it better. Vehicles moving at high speeds need certain amount of mass for their relative size to keep them stable. Take too much away and safety and handling get worse not better.

Perhaps a gyroscopic stabilization unit could compensate for the lost weight....
