how have you beaten a speeding ticket

Only by not getting the ticket in the first place. I've gotten out of a couple of tickets by telling them from the get go that I knew why they pulled me over, etc. and the cop's decided not to give me a ticket. But once you get the ticket, it's a whole different ballgame. It's almost impossible to get out of it completely. And people say that cops don't show up in court, but unless they've issued a completely bogus contempt of cop ticket (usually not a speeding ticket), they do.
