As my high school drivers ed instructor always said: "Colored lights are physically incapable of stopping a moving car."

If there's one thing that I've learned being a pedestrian in NYC for the last 10+ years: Traffic lights are very loosely correlated with driver behavior. In my experience, you're far better off making decisions based on observing cars and drivers than faith that a red light means anything to a cabbie in midtown during rush hour.



See above: "Situational awareness is good. But walking on red carries a bit more risk than walking on green, all other things being equal"

Trust me, even in NYC, cars are slightly more likely to drive on green than on red.

Or, in other words, a green light is a necessary but not sufficient precondition if you want to achieve minimal risk for your crossing.
