You wanna try something fun? But you gotta have balls to do it. Book a court date ask the officer in front of the judge how fast you were going, and he will say 81km/h in a 50km/h. Then you say yes that is true, I was going 81km/h in a 50. Then show them the ticket and say However this ticket says I was going 65 in a 50 so obviously either the officer is wrong, or they are lying. The ticket will then get thrown out of court.
