In my younger days as a bicycle rider I found that I could usually trigger
the car detectors for traffic lights by riding my bicycle so that the wheels
ran exactly over, and in the same direction as, the cuts in the pavement where
the wires for the car detector loop were buried. I would usually stop to wait
for the light to change with both wheels sitting on this cut.  I have not
tried this in 10 years, so your mileage may vary.
