If you were doing almost 30mph over the speed limit (and they will typically write you as less if you are polite), then to me that is reckless driving. I think anyone who does this shows a reckless disregard for the safety of other drivers, and should not be allowed to drive and should have their license suspended for at least a year on first offense.
What you think there is to 'fight' in court, I don't know. You are lucky you weren't arrested on the spot and your car impounded.
In most states, Reckless Driving is defined as driving at a speed 20 mph over the speed limit, or in excess of 80 mph. The penalty for reckless driving is usually up to one year in jail, and/or up to $2,500 in fines.
