So in Phoenix we have way to many damn cameras. Well i have seen 3 bikes do this so far. So if your in the carpool lane the censors on the ground end about 9/10 of the lane. So that 1/10 is open and i seen the bikes get over so they are pretty much on the line or they get over in to the shoulder just a tad bit. One bike actually was going over the speed limit i was doing 70 limit is 65 he was going faster then 75 im sure of it well i saw him get over to the line and no flash. So is there really a way to cheat the system? or did he slam on the brakes right before and just get lucky?
