I have a problem with certain left turn traffic lights in that they do not sense my bike! When traffic is light, I will come up to a left turn signal (in the left turn lane) and wait for the light to change. Modern computerized lights do not change to green unless they sense a waiting vehicle. The sensors are loops in the pavement. At one intersection I stop directly over the loop, then the light changes. Most intersections I can't tell where the loops are and end up sitting there for several cycles of the lights. If traffic is clear, and light is green for through traffic, I then go ahead and make my left hand turn. Anyone else have the same problem?
