I agree, we should take half the space currently allocated to car traffic and turn it into sidewalks.

Until then, however, we should live up to the "sidewalks are for pedestrians" idea. DPW should tow cars that are parked on the sidewalks, every block of road/street in the city should have sidewalks on both sides that are wide enough for two wheelchairs going in opposite directions to pass without leaving the sidewalk, and there should be strict limits on the number of curb cuts in commercial areas to ensure that people using the sidewalk are safe.
