About pedestrians and drivers:

In order to drive, it is necessary to have the rights and KNOW the PD (ideally, of course - exclude unicoms, who buy the rights and chase the streets, without even suspecting that there are rules). However, pedestrians are not required to know the PDD, and in some situations they begin to water drivers passing through the pedestrian crossing on a green light for pedestrians. They, unhappy, do not even realize that if the car is stuck in the center of the crossroads, missing the opposing cars, it must STOP the maneuver, even if it is already on the red light. And pedestrians, seeing the green for themselves, immediately break on the road (and sometimes without waiting), thereby creating emergency-dangerous situations, not missing the "later" cars.

Bring it to the best plz, maybe at least someone’s brains will add...
