They actually catch quite a few people doing that Spray. Especially in areas surrounding metropolitan areas or highly affluent neighborhoods. People do it, I see it, you see it, but they are only NOW enforcing it strictly.
Ya becareful when driving near the end of the months, cops will look for anything to pull you over. They have to meet their quota for the month. Sometimes here in Modesto a pack of cops would line up together and then pull ppl over for stupid reasons. It's retarded... Since we pay then with our tax money.
