Given that drafting is dangerous, given that Mike S. probably wasn't
implying drafting, the question remains, does drafting affect the
cooling system significantly on a water-cooled vehicle?  Additional
question, assuming you are not drafting but following at a safe
distance (3 second rule), would you be outside of the lower pressure
zone behind the truck in front of you?  Just curious...
