Don't know if this will help but my boss got a speeding ticket. He didn't go to traffic school, but instead went to court to claim that he wasn't speeding. (He was flagged for going 70ish in a 65 mph

) The cop that got him never showed up so he got off.
Now if you were going 90 on the freeway, I don't know if I can help you. But if it was a minor speeding, see if you can just go to court. Most likely the court date will be set 3 months from now and it's enough to come up with some BS response and long enough for the cop to not remember your face at all.
I'm not advocating this... but I'm just telling you what my boss did to get out of it.
