End of the Month Mayham

So I was coming home from Texas Tech University in Lubbock after a college visit, and i never thought that I would end up getting pulled over three times during the 250 mile drive. Any advice on the following would be greatly appreciated. First time: There are many small towns through this highway that you have to slow down for. I was passing through one of these when I get lit up after I pass through the town. The officer claims that he followed me through the small town "pacing" me at 55 in a 45. I have a major problem with this. I have recieved a few tickets before, but this is one that im seriously considering fighting. I know for a fact that I was going 45, because I know that all these small towns are the ones that will get you. I didnt see any cars close behind me, so I beleive he read 55mph in an attempt to catch up to me. I just think its really wierd that he caught me at such an even number. 55. On the ticket, it also says that I was caught in "heavy" traffic. I was the only person on the road, but I guess in a small town, if you call the cop and you as the only people on the road, its heavy. Second time: I revieved a written warning from a state trooper for going 68 in a 65. Third time: I recieved a verbal warning for turning off my brights too late. So I have 2 things... 1) do cops really have a monthly quota to meet. and 2) if any cops can help me out with the "pacing" technique, that would be great. sorry about the length.

i dont think that 10 mph exists in TX becuase i've never heard anything like it, but even if i had, theres the other problem... im on deferred for another ticket (which is another reason why i made sure i didnt speed)
