Tim Rogers of D Magazine wrote about the Central Expressway speed trap that exists called Fairview. If you don't know about Fairview, it's that's small city of 9,000 between Allen and McKinney east of Central Expressway. It makes up for its small size with hustle on the highway. Mile for mile, Fairview writes 3 times as many traffic tickets on Central Expressway as McKinney, and a whopping 35 times more than Allen.
