Traffic sensors for signals
When I am tooling around town, I occasionally run across a traffic sensor that trips a signal red for a cross street, so that I can cross the intersection. These are usually just before the crosswalk and are embedded in the concrete. I used to just ride around in circles waiting for a car to show up and trip the signal because my bike was invisible to the sensor. Well I found that if I stop and lean the bike on it's side so the frame is parallel to the ground instead of perpendicular, then the sensor "wakes up" the light, I pick up the bike and continue on my way. I was so happy with this discovery that I rode around and tripped a few just for fun (I am easily amused, I guess).
My frame is made of steel. I was wondering if anyone can confirm this works with an aluminum frame as well.
