I ride as a VC most of the time, but I always get frustrated at the lights at intersections. The lights are weight sensitive, so for the most part they only change if a car is waiting, or if a pedestrian pushes the button to cross the street.
I am curious how other VC's get around this? Maybe your city does not have a set up like this. Maybe you just wait. But if I was to wait at an intersection I could be sitting there 5 minutes before another car pulls up and triggers the light to switch.
