Here we go again, whining about speeders.

Type in : Police ticketing slow drivers. The two top complaints are: slow driving (especially, in the left lane), and tailgating.
Is it any less safe to be driving 10, 15, or 20 miles below the posted limit, than it is to be driving 10, 15 or 20 miles above the limit? I do not think so.
