And it's not just about the width of the sidewalk itself, which is not too bad, since despite being downtown this particular stretch is not as busy. But most places with sidewalks this width will be either along a less busy street, or if they are along a busy street, they will have a landscaped boulevard strip to distance pedestrians from traffic, sometimes quite wide like on some suburban arterials. They'll also have buildings with bigger setbacks so that if a vehicle loses control and starts going onto the sidewalk, pedestrians have more room to escape onto the grass.
