For those of us that need to walk while the powers that be figure out how to save us from cars, my suggestion is to assume that they can't see you. Because they probably can't. No, they don't see you when you cross the street when the light is green for you. No, they can't see you when you cross the street on a 25mph school zone. No, they can't see you when you walkway is closed (for construction) and you need to walk onto the road for a bit. And, they especially can't see you at night.
If you make eye contact with its driver, then maybe they've seen you. Otherwise, they can't see you.
