Here’s how the hoax unfolds. First, the DPW illegally posts unreasonably low speed limit signs throughout the town. Nevertheless, studies consistently show that the overwhelming majority of motorists seldom pay close attention to speed limit signs. Instead, most motorists instinctively drive at a speed that is reasonable and proper, having regard to traffic, type of road (e.g., highway vs. thickly settled), and safety of the public. Speeds at or below the 85th percentile are reasonable and proper by definition. Phony low speed limits only flip the statistics, so that most motorists now appear to be speeding.
Second, the police strictly enforce the phony speed limit signs, which almost every motorist now exceeds. They dutifully issue bogus traffic citations for Speeding in excess of the phony speed limit signs.
