Some people will brake hard if they see a pedestrian who is merely near a crosswalk. That pedestrian may just be standing two meters from the crosswalk waiting for a ride, but some drivers will still stop. Stopping for people actually in a crosswalk would be fine, but there’s a certain competitive niceness here, so people brake hard and brake often.
I wish that was the case here. Literally no one cares about crosswalks or if there are pedestrians waiting to cross or even if there's pedestrians crossing WITH the walk-sign on. If they see someone wanting to cross, they speed up to try to beat them. If there is someone about to cross, they speed up and swerve around. If there is a vehicle slowing down for a pedestrian to cross, they speed up, swerve around to overtake the car to get there faster before pedestrian. Ridiculously stupid drivers.
On a related note: there's also a number of cyclists here who have taken to recording every second of their ride in hopes that they have the law on their side, except they soon find that reporting incidents to the police with footage evidence does nothing, because there is a law stating that an officer has to be personally present when the incident happened in order to administer a citation (unless it's footage taken by a city-installed traffic camera). Just two weeks ago the police shot up a driver for turning too close to an officer (the vehicle was considered a weapon), yet a few days later, a cyclist reported footage of a driver dangerously over taking him on the same lane, then telling him it was "to teach a lesson" afterward and they were completely dismissed. Humans are feral creatures, ladies and gentlemen.
