By WS do you mean Winston-Salem? I wholeheartedly agree that everyone should boycott the area, patronizing it just lets the city council believe they've done well.
Our cops pretty much don't do traffic, excepting the MC cops on the 52 and occasionally B40, unless there's been some complaints about traffic from the constituents, a special event, or they live in the area, the majority seem to reside out of town though. Were there by chance two officers in the car? They recently graduated a class that's FT'ing right now, and FTOs gotta keep the rookies entertained somehow.
Otherwise my suspicion would be you were either doing considerably more than the limit, pacing traffic doesn't matter if you're the unlucky one, there may be signs down (useful for court), but there are no dark signs, just inattentive drivers, option B there was something else about you that got their attention and the speed was PC.
Uniform car or unmarked Charger/Tahoe? Get the car number? Just curious, can't actually help.
Go to court, give the officer something to do besides sit in the hall and get paid. Sounds like you already got the deal an attorney would so likely not much that can be done.
