Well, if you're doing something irresponsible, good...glad you got nailed as you knew better and did it anyway. Simple speeding is a different story, getting plugged for doing 7mph over on a highway is just stupid and pointless (as has happened to me, was being passed by an 18 wheeler at the time as well).

So yes, I'd fight a ticket if it was pointless. I had no idea that you were being reckless and irresponsible in the eyes of the law.
