IRT Clifton Uyeda - If you find it difficult  "to keep track of all of these situations around us",  I suggest you stop worrying about people that "enter any crosswalk once the do-not-walk red blinking lights start to flash.".  You should only worry about people in the crosswalk when the "do-not-walk" signal is ON (not blinking) which is when you can drive through the crosswalk.  As long as the "do-not-walk" light is blinking, pedestrians, not drivers,  have the right of way in the crosswalk
