I bike to a park and ride and bus the rest of the way to work. Leading up to the park and ride there is a bus only lane to help the buses get around traffic and congestion. Typically this lane is empty so I use it, more or less, as a bike lane. I stopped at the light on the car sensor and the light turned green for me first while all of the other lights were red. The intention is to allow the bus to get over a few lanes to make a left at the next light but it works for bikes too! Could be a useful tool to help get across lanes ect if you have any in your area.

Sidenote: I can trip any car sensor with my aluminum bikes as long as I park the drivetrain directly over the metal strip.
