As a point of reference, driving 81 on a 60mph zone in San Jose, CA, cost me $213.50 for the ticket alone, or $227.50 + school fees to take traffic school. I asked the clerk if the fee would be different if I had only been going 79mph and the clerk said no.
On November 2, 2009 I got a speeding ticket for going 82 in a 65 in ventura county. My ticket was $380, or $437 if I wanted to do traffic school. My ticket was an infraction for exceeding 65.
hope this helps
