Keeper75:I think the sensors at the traffic lights rely on magnetic induction to induce a current in the loop you see in the road. (If I've written that incorrectly or badly then please correct me.) So a large metal object say a car or truck has no problems. A smaller vehicle like a scooter may have some problems at some intersections.
Yeah, Keepers onto something here.
What you need to do is get yourself a utility belt, and fill it with strong magnets, this will assist in the sensors detecting you. The stronger the magnets, the more the sensors will see you coming, thus opening up all the green lights for a quick trip to work.
