Earlier this year, Berliner Newspaper Der Tagesspiegel reported in Berliner Grundschule kapituliert vor Rasern (article in German) about schools in Berlin Schöneberg taking down their school patrols because the job became too dangerous. Apparently parents bringing their children to schoolby car because traffic in Berlin is dangerous are driving so recklessly that traffic in Berlin too dangerous. Also, said parents were giving a shit about school patrols orders and signage, speed limits or other traffic rules.
The saga continued with a second article (article in German) about schools in Spandau having the same problem. Because of the situation, parents instead of pupils have been employed as school patrol, but to no effect.
First reactions from politics are in (article in German) – now the police are posting speed cams in front of schools, and are doing school patrol work in some particularly affected schools. Also, temporary road blocks (1/2 hour before school begins) are being suggested.
Not just in front of schools, but throughout the city, cycleways are often blocked (article in German, many pics) by parked cars in an extremely dangerous fashion.
