Most of my issues with non-responsive traffic signals are when I'm
trying to turn left and the left arrow doesn't trigger. Putting a pole
in the middle of the road where I'd be able to reach it doesn't seem
like a very safe thing to do whereas making the loop detectors
sensitive enough to detect my bike wheel is safe, convenient, and
frequently requires no additional expenditure beyond proper training of
the personnel who adjust the sensors.

True, provided that the sensitivity is properly adjusted.
Unfortunately many are not adjusted that way until enough cyclists
complain and someone from the transportation department has to come out
and readjust the sensor.
