That ramp isn't really a ramp. Oddly enough there are at least two of us, on this board, who were present when an OPP officer estimated the speed of a group of motorcycles, by sound, and got it right within 5 Kmh.
Guessing speed by sound is not also accurate enough maybe he was lucky. What if somebody has a voodoo straight pipe and someone has a oem muffler someone can go twice as fast and sound quiter just saying. I've gone flying by cops with a stock muffler and they are too busy reading the paper or munching donuts.
