Legal Help That Doesnt Involve Weed

So as it says I need some help.

      This is about a traffic violation that i received a few days ago (Thursday). Its a long story so bare with me for a moment because i believe all of the details are important.
     So ill will just tell you the story. The other day I just bought myself a new car. The day after i decided to take a short road trip to ride some bikes in a city that wasn't iced over. On the way back home I was driving down the interstate actually going the speed limit. When I was passed by a driver that was going probably about 100.. At this point I had owned the car for about 32 hours.. When the driver passed me they spit a bunch of rocks at my car and cracked my windshield. Now I know that, that was incidental, but if they hadn't passed me at such a high speed not as many rocks would have been thrown up with that amount of force. So I caught up with the driver and decided to fuck with them a little bit because i believed if they weren't driving like a jackass my window would be fine right now.

 But anyways for about thirty minutes I wouldnt let them pass me. I was in the left passing lane and when they tried to pass me in the right lane I would speed up so they couldnt. Technically your supposed to yield to the right lane for faster moving vehicles, but at the same time I believe I legally had the right to be the in left lane because I was still passing vehicles.
  But what I think actually got me was when they pulled their truck off the interstate on some off ramp to a tiny town. I then drove down the interstate pulled off as well and waited. but long story short. during this whole time I wasnt tailgating them, and I didnt ever technically cut them off because I never left, the Left passing lane. I was failing to yield to faster traffic, yes, but that isnt what it says on the ticket.. the ticket is a reckless driving ticket for the negligent disregard for the safety of myself and others, and CUTTING OFF, and HARASSING a FEMALE DRIVER.

that whole time I had no idea the driver was a female, and i was confronted and had my report taken down by a female cop. A male cop gave me ticket. When I got back to town there was a sheriff waiting on the exit for me who followed me. A highway patrolmen a few blocks down that pulled out and pulled me over. seconds after I got pulled over a third officer came screeching into the parking lot. I think i may have a case against gender discrimination, but basically I dont want to pay for this ticket because as I said, I just bought a new car, that classifies as "sport roadster" that i know the insurance will sky rocket on if i plead guilty of this charge. That and im a broke college student and i have enough bills that are tough to pay already. And also this ticket is 300 dollars.  I dont have any bad driving history so i think that may help, and ive had a license since i was fifteen and a half without any prior charges. This all happened in the state of Montana, and any advice on the direction to take this helps. Im pleading Not Guilty, but i need some direction as to why i wasnt LEGALLY doing anything wrong. IF you have made it this far. thank you and any Advice is appreciated
