In essence he doesn't have to prove he was going 75, he will have to show its an inaccurate read and best regards to you as well sir

And one more thing the angle increases the measured speed increases
-
You all seem to be pretty hard on this guy. Where are all the supertruckers who brag about their truck doin' 110 up the grapevine?

I used to run with Monfort trucks, then common sense got the best of me.mp4694330 Thanks this.

Actually it doesn't show any inaccuracy, and it is not an error but rather a known effect.
The known effect is that the radar will "always" under report and will never over-report because of the cosine effect.
Not really. In order for you to show any discrepancy regarding actual road speed vs radar speed due to cosine, you have to show that you were going faster than the radar reported (Because that's what cosine effect does).This is somewhat self destructive to do in front of a judge.
For instance tracking a vehicle approaching a radar unit (Consider curve or hill) would look something like this on the display. 65-65-64-64-64-63-63-62, but the actual speed of the vehicle is higher (Benefit goes to the target), while a target headed away from the radar unit would look something like 62-63-63-64-64-64-65-65, but again the actual speed would be higher(Again benefit to the driver).
Additionally cosine effect is a known effect of radar and angle which is easily explainable, calculable and accepted. It is known for instance that the closer the target is to the radar unit, the lower the measured speed is to actual and cosine effect can be easily calculated (Using basic geometry) as long as the angle and distance are known. Judges also know (Or should) that the cosine effect works in favor of the driver at the time he was targeted. The only time cosine effect is detrimental to the target driver is if the angle is so severe and and the correction by the unit shows a ridiculously high speed which would indicate the radar unit was tracking a different signal, which is the operators responsibility to recognize.
To visualize the cosine concept, think of a target approaching or departing at 90 degrees. This would mean there is a 100% cosine error, and the radar would display 0 mph because the vehicle is not coming toward or going away from the radar unit (True speed of the target could be any speed, say 100mph). 89 degrees would show a small speed, 88 degrees a little more, 87 a little more and so on until true target speed is displayed when there is no angle between target and radar unit.
Sorry, did not mean to run on, but I did want other readers to see the concept.

Absolutely not correct.

Well. Sense the OP disappeared, at least we're learning a thing or two of how radars work.
Balakov100 Thanks this. -
Ok I should word it like since I worded it wrong, my apologies. The greater the angle the greater the error.
-
As far as the OP is concerned, I have always been of the opinion that if you are speeding (Or anything else) and get caught, then be a man, pay the price and move on. If you do not like the price, don't do it again. Other than that, no need in bashing someone, they either learn from their mistakes, or they don't.
Best regardsx#1 Thanks this. -
Uh oh......you ready for this...palm to face. I'm over here arguing my point and I have it backwards lol. Ooooooooooooops lol feel like an A-HOLE. Had to call my old Lt and he said nope. Your wrong. Its the other way around...my advice now. Pay the fine lmao
dibstr nice job. My apologies
