Whoa boy, lots of stuff, but not going to bother quoting it.

RE: plea bargaining, I wasnt referring to simply a lower cost fine. Moreso, a points reduction, for example from 6 to 2. Or BETTER yet... moving to a non-moving violation, that has happened on more than one occasion for me.

I used to get popped all the time, then I grew up and stopped driving quite so fast, because you gotta pay to play, and it became prohibitively expensive.
I once was popped for 120 in a 65, mandatory court appearance. This was in CO, we lived in WY at the time, and were nearly late to court (physics final), showed up and the LEO did not. It was dismissed immediately. Fortunate for us, as we had ~$1200 in violations. I was driving, buddies car, so we both had to be there (at least it made sense to us at the time). Senior year.

Another time, I was cruisin 100 in a 65 (again I-25 near Ft Collins), LEO was decent and lowered it to 84 in a 65. Took a chance and went to court. Again, she didnt show up and case was dismissed.

Ones that I just got popped and paid were:
97/45 ($300+)
103/55 ($500 + 2 weeks community service)
107/65 ($500+ + month community service)
Cleaning the shoulders/medians is NOT fun, especially with the county inmates.

My ins rates were not good from 16-24 as the last ticket I got was when I was 21 and the 3 years for it to drop off the record.
In WY, 4 tix in a year and you loose your license. It worked out that I always had 3, ten when it dropped down to two(after a year), I would get the third again.

I finally sensed up and decided it wasnt worth it and stayed clean for 12 years. I did get popped this year for 51/40 (amazing sunrise on the way to work and not paying attention to the speed, alone one on the road).

I did contact the DA and got leniency for my clean record and moved from the 4 pointer to a non-moving violation, with a fine (revenue generation).

Ive been there, I live to drive fast, but learned that it is best saved for the track. Cruise control is your friend.

Talk to the DA and see what you can work out.
Good luck
