I know you're mad/frustrated and I'm going to likely piss you off, but it's CR, relax and take the following with a grain of salt.
You were likely speeding. Even you know it. Slowed down, moved left to pass, etc....80 or not, you got busted. Shit happens. That cops not likely out to make shit up. Especially if you as you say you weren't over 70mph. A bored cop wouldn't bust you for 70 in a 65. He could easily just wait 3 minutes and bag another guy going 80mph. In that area that spot and those cops are there all the time. Know your route and keep an eye out. I drive there all the time you might not and that I understand. Still, that areas been a trap zone for 25+ yrs, / since I can remember. You signaled and pulled over? May as well admit you're guilty. $100 and 2pts is nothing. Seriously. If my next ticket could be gauranteed to be that easy, I'd pay it in advance right now.
Carry on.
