I had my share of speeding tickets in college - mostly from driving in rural areas long distance going from city to city. Most times I just bite the bullet and complete a stupid online defensive driving course and pay the court fees.
That said, ever since growing up, getting a job, and living in the city I haven't had any issues. There is always a bigger fish to fry, so everytime I'm going 75 on the 65 mph highway, I can usually slow to 70 at least and they don't chase me.
I have heard though that plenty use our hyatt legal benefit from our employer to get traffic tickets dismissed. I've also heard that an easy way to get them to dismiss the ticket is to keep delaying the court date... Reason being is by default the originally assigned court date is a day in which that cop is DEDICATED to being in court. So there is little to no chance you can ever get it dismissed via court. HOWEVER, if you delay the court date and push it to a date that the cop isn't designated to be at it's much more likely he won't show.
YMMV, and I've never had to go this route, just something I've heard.
