A small note about how speeding ticket fines work in SoCal (to my knowledge). For each MPH you go over the speed limit, it's five bucks. So if you're caught going 75 MPH on a 65 MPH freeway, that's 10 MPH over, and $50 down the drain.

It costs extra if you don't pay on time and/or if you take traffic school. (That's not the cost of traffic school itself which is usually another 20-40 bucks, just the cost of the court having to process the fact you took traffic school)
