<human>: Summarize the given text in a few sentences.

Hey guys, just got a speeding ticket and I believe I actually have a pretty good defense using time speed and distance calculations to prove obstacles that would prevent officer from getting an accurate radar reading.

I will file discovery tomorrow.  What kinds of things (pertaining to radar and using radar etc) should I request in my discovery?  

I have heard people say you need the records that relate to "tuning" or "certifying" radar etc... or classes for the officer.

What say you?  Also, if you have beaten radar tickets would love to hear your story.
<bot>: I reduced my $90 speeding ticket to a $67 Failed Windshield Wiper ticket by filing Discovery and then talk with the Prosecuting Attorney.  Didn't even have to go to court and no Points to my record.
