Try touching your toe clip (assuming you use them) of the pedal you've
removed your foot from to the sensor.  Most will reach if you lean the
bike a bit or use 175mm cranks like me.  Also, angle the bike across
one corner of the sensor.  That seems to do a better job of interfering
with the EM field.

I live in California also, and this has about an 80% success rate.

It angers me however that the state can declare a bicycle a vehicle
and then interfere with its safe and efficient operation with these
ridiculous sensors.  My motorcyclist friends have the same problem,
incidentally.  Does anyone know if these sensors have adjustable 
sensitivity?  They are based on a metal object interfering with a
magnetic field, so I should think so.
