I sure hope you aren't selling your book. Your "understanding" of lidar speedn
detectors is poor at best.
You should check out the specs on the lidar used and calculate just how large the "spot" was. The minimal error caused by not hitting the "exact point" (if you calculate the actual size of the spot you will realize how invalid your claims are) will not cause an error large enough to make a difference. You should also realize that there are several hundred, at least, measurements taken during a speed check, all in less than half a second, which allows for a very accurate measurement.
