I've read testimonies of a real traffic court and basically people do all kinds of defenses like radar tuning and they just finds them guilty. There was a lady who was ticketed for not stopping at a stop sign and she brought in a huge blown up picture showing that the stop sign was obstructed and the cop just lied and claimed there was a second one and guilty. Traffic court is a kangaroo court.
If you're ticketed and dispute it, first you spend hours in court. First waiting in line, then sitting in a court room with 20+ other people with the judge talks to some prisoners on another case for an hour. Then they show you a video and that's it. Then if you want to plead not guilty you wait and later you you meet with a prosecutor who you can plea bargain. Then you get your court date and the cop is notified to show. The first one he does not have to show. The kangaroo court has various illegal things like how the chief witness and prosecutor usually are the same person and how the judge also acts as the second prosecutor and if you mention this fact in court, the judge will find you in contempt of court.
Sometimes you can't plea bargain, but basically if you rarely get a ticket and want a clean record then plea bargain for it to be made a non-moving violation which they might do. If you get a really bad ticket like reckless driving, DUI, or whatever and don't think you can win in court, then plea bargaining will work.
Generally how to win is you do whatever that stuff says, then you go through 2 hours in pre court, hours more in the kangaroo court where the cop shows up. Then you appeal it to a real non-kangaroo court an then you win. Sometimes in both criminal and civil cases, people can do an array of appeals over and over again up to the supreme court and usually get stuff overturned that way.
I also didn't watch the video, but I've read lots of stuff beforehand. The video is 115 minutes and it's google video. Google video buffers 5 seconds and then just won't load anymore usually.
