I was thinking in your case, maybe you could calculate the distance required to reach the speed that the officer claims you were traveling. It might turn out that your vehicle isn't capable of reaching that speed or maybe it is capable but could add doubt.
I would probably be one who will actually put together a spreadsheet detailing any and all possibilities that such a formula would put forth. So I'm not taking anything away from your suggestion.
However, I'm not sure how well this will work especially considering AVID's statement about being
stopped at a red light and the accelerating towards another red light. Especially since that sort of calculation is based on the premise that a driver pushed it to its maximum capability.
More over, time/distance/speed calculations require us to know 2 of the 3 variables. We know the distance, and he can use the time that the officer notated on the citation (although that is the part he is disputing). And even if he wasn't disputing it, that calculation will only justify he officer's claim.
One can deduce the maximum speed (that you suggested) over a certain "known" distance by knowing the maximum rate of accelaration of the vehicle but that is a variable that Avid would be hard pressed to claim knowlege of especially since he was driving what he described as "a long truck" and his rate of acceleration can vary depending on how big of a load he was carrying if any.
Point is, a defense that includes mathematical calculations, may tend to test the court's patience, and knowing that you want to sway the judge away from siding with the officer, getting on his last nerve might cause more harm than benefit.
I believe in math.. and if the math doesn't add up, and all factors are included correctly, it didn't happen. I'm no expert, maybe someone more experienced can comment on how this would hold up in court.
I am neither a mathematician nor a law expert... But I would venture a guess that the more complicated your reasoning might get, the less chance of you being able to cast any doubt over what a sworn officer may testify to.
I don't know if this has been said here but in my view, questioning the officer about his location in an attempt to cast some doubt as to his ability to pinpoint exactly when Avid passed the "zero point" and when he passed the "95 foot point" would blow the officer's entire calculation out of any "reasonably accurate range".
Example, just by assuming that the officer could have had a 1/8 of a second delayed reaction time to start the timer and 1/8 of a second early reaction to stop it, adds a 2/8 of a second (0.25 seconds) error time to the calculation.
So: 1.63 seconds + 0.25 seconds = 1.88 seconds
Then: (0.018 miles) / 1.88 seconds = 0.009574 miles per second
0.983 miles per second X 60 seconds/minute = 0.5745 miles per minute
0.5745 miles per minute X 60 minutes per hour = 34.46 miles per hour
34.46mph - 25mph speed limit = 9.46mph
Which places him under the 10mph over the limit that is allowed in PA.
If the officer argues to the judge that he has a quicker reaction time than that, then surprise him by throwing your pen at him and see if he catches it...
JUST KIDDING... DON'T THROW ANYTHING AT ANYBODY!!!!!
