Ideally CCTV should also be used to prevent red light runners. Run a light and get your ticket in the mail. With each infraction your fine grows exponentially. Also having marked police cars would do more to prevent speeding and driving crazy because as I mentioned, they don't have to pull anyone over and seeing a cop car causes most people to straighten up. Plus the way I see some cops driving it makes me wonder why I can't do the same.
