Cops can always find a reason to pull you over. Also, they have no obligation to tell you why they did so. 1 mph over the speed limit? Valid traffic stop. You slowly drifted from the right side of the lane to the left side? Valid traffic stop in the eyes of the law.
Is it bullshit? Yes. Illegal? No.
Is the driver in the OP still required to provide his license when pulled over?
Yes.
Ah, so I should divide all of the numbers in your graphic in half to get to something reasonable then.
