I never got a speeding ticket. I usually drive 5-10 MPH over the limit on the freeway. I stick to the limit on residential streets.. Now that I am in California, I have learned you have to keep up with the pack. If they are all driving 80, I'm going 80......if not, they'll just run you down. C.H.I.P.S will catch the leader.
This is the only state I have ever lived in where they think it's all right not to yield coming onto the freeway. They just come on and you'd better know they are coming on and cutting in. If you don't adjust your speed to let them in, they give YOU the dirty look or finger. The actual rules are that they have to yield, but it never happens that way.
