Are you kidding?
How does slowing down keep people from passing each other? They’ll just pass each other at slower speeds now, so it will take even longer.

Whatever. If they have a little more speed left in their rig than they can get on around if they choose to.. Most of them I experience doing this are running between 65-70 and can’t gain on the other rig thus they run for a long distance side by side until final the truck passing gains enough to get back over.
