Funny, this has just happened to me, the officer said I was doing 100mph and I told him this was impossible in my truck, I drive a 2003 chevy suburb. This has a govenor on it that if you go 95mph the fuel shuts off . He was not happy about my responce, he sighted me and no sooner did I get back...
I would file a motion with the clerk of the court, and I would ask that your case
get dismissed due to the lack of evidence and due to the fact that the DA has not
been able to give any documentation to the judge as requested.
