think twice about giving you another BS ticket since you have shown that you can defend yourself. Also, judges can sometimes be unimpressed if they see that cops keep picking on one guy repeatedly for minor offences.
On the other hand, since speed limits are set *so low* and some laws are so vague that cops have lots of power of discretion to bust you for minor offences. This can definitely be a pain in the ass.
I still think this shouldn't dissuade you from contesting the ticket though. It's the right thing to do.
