I check to make sure that drivers are actually going to stop are are stopped, then move swiftly across when walking. If a light goes green as I am approaching when cycling, I will treat that like a spring point and try to make it if it looks like I have a chance to do so safely.
Walking across like Tim Conway's 99 year old firefighter is just asking for some impatient idiot in a jacked-up pickup truck with the big mud tires to run you down.
