Interesting series of videos on YouTube by a wheelchair user about using sidewalks in a wheelchair. This video shows how cars parked on the sidewalk portion of a driveway and curb cuts and sidewalks in disrepair obstruct passage.
This happens in my neighborhood as well, forcing me into the street.
Love the part where a neighbor notices his open car door is in the way and closes it. Super nice. Important to show the positive parts about sharing the sidewalk too.
