I don't think it's very likely that you could beat a traffic ticket based on "it's unfair." People do still get pulled over for going 5 over. People do not get pulled over for going 5 under, because going 5 under is explicitly legal. What even is this argument? You're seriously going to draw a comparison to a genocide because I said speeding isn't "just as legal" as driving within the legally proscribed range of speeds?
