My city is slowly, as budgets allow, converting to optical sensors. Can't happen soon enought for me. If I get stuck with a red that won't change, I'll wait for a while, hoping for a car. When I get sick of waiting, I'll go when it's clear.

What bugs me even more is when a car does come up behind me, but won't pull forward far enough to activate the sensor. There are drivers around here that will pull up to just a yard behind another car/truck, but keep 15 feet behind a bike stopped at an intersection. Crazy.
