I too will trust traffic and transportation engineers over the big mouths
in government and insurance companies.  My guess, however, would be that
the practical speed limits for trucks would be lower than for cars, not
because of weight, but because of vehicle stability.  A small low vehicle
with four wheels at each corner has to be more stable than an eighteen
wheeled vehicle with a high center of gravity towing one or more trailers.

Rather than slowing the automobile down to match the truck, some speed
differential may be desirable.  I am sure the engineers could calculate
the optimum speeds for both sets of vehicles, minimizing both speed
differential concerns, and stability concerns, while maximizing average
speeds for each.  Those optimum speeds, I am sure would be nothing remotely 
close to those chosen by our government which sets speeds arbitrarily.
