You know the ones - the lights that are supposed to be triggered by sensing a car waiting. Not a bad idea in itself, but if you're on a motorcycle at the light, shut the bike off and have a snooze because the light will never fucking change! Even two bikes side by side won't do it. So I've had to treat them like stop signs and (carefully) run the red on more than one occassion. Just waiting to get hauled into court on that one.
