This all reminds me of a trip we took to Jacksonville when I was in Kings Bay. We were headed over to the Regency Square Mall stuck in stop and go traffic on Monument Rd. A guy tried to make a left turn in front of me, and instead of letting him in, I gunned it and flipped him off (my head turned to the left the whole time, making unbroken eye contact with him).
When I thought I'd said (or extended) my peace, I looked forward to see the brake lights of the car in front of me -right in front of me-. It was too late, and I ended up hitting the guy at about 20 mph. My wife was yelling at me the whole time, I tuned her out and just figured she was mad I was giving the guy the bird.
Got cited for careless driving (thank God it wasn't worse) and got it knocked down by taking a driving class online.
To this day I'm jealous of the experiance the guy I flipped off got to have. I think I'd pay to see someone flip me off in traffic and rear end the car in front of them.
Good luck with your tickets, based on what I've seen here, I think you'll be OK.
