Besides likely being less effective than saving such arguments for the magistrate, what exactly is wrong with that? It's a standard avenue of contesting a speeding ticket.
Because you're admitting that you were speeding. If you claim ignorance ("Sorry, I was too focused on traffic to glance at the speedometer"), you at least have a chance (depending on the officer's mood) of getting away with a warning.
I agree you're better off trying a different tack with the ticket troll, I'm just saying it's not wrong.
