Two spots I always encounter that are I-75 South to M-59 East and I-94 West to Rotunda exit. 1-2 miles before the exits, the right lane is doing 50mph in a 70mph zone.
I know, I see it at every Michigan left, off ramp, intersection and the truly useless do it at every right turn. It's like they almost come to a stop at the apex of the turn.
