CHP? What CHP? San Diego County has the least density of cops per population of all U.S. cities. With the huge debt the city has, there is no budget to hire more. In addition, many experienced cops have left the county citing the high housing and living expenses.
When there is no traffic on the freeways, I drive at 80 mph constantly; on surface streets, at 10-15 mph above the speed limit. Have been doing it for years and never get tickets.
You are right about the fact that San Diego is aquiring that big city feel, lots of traffic; everybody is angry and in a rush; noise and air polution.
