Now that I live in Toronto we face the same challenges. Politicians may introduce traffic laws to curb dangers and nuisances from drivers, but police refuse to enforce them. As they don't live in the city, cops seem to prefer to side with drivers over local pedestrians, residents or cyclists who they view antagonistically. Broken window works for them because they enjoy harassing pedestrians and residents of the communities they commute into.
So there is a bigger problem to solve than legislation.
