...but surely this is something most of us hate to see. I walk on this street near where I work a couple times per day. Granted, the sidewalk isn't much to speak of, but cars park like this all the time. Sometimes people park utility trailers or campers covering the entire sidewalk. If I see someone doing it I will let them know they should leave at least enough room so someone in a wheelchair wouldn't have to go out in the road, and this has been fairly effective, but for most this seems to be acceptable behavior around here.
The thought crosses my mind, but I wouldn't do that. What I do always try to make a point to do is walk on the sidewalk side, even if it's really tight so that hopefully they will notice someone is uncomfortably close to their precious car/trailer/camper. Hopefully they will think it's going to get scratched and leave more room next time.
Turn the living room into a garage. Or the front yard. Parking a car in front of your house isn't a right. In a perfect world: If there is no space for parking, then it should be considered to just not own a car.
That's very dependent on there actually being another way to get around. Public transit isn't good everywhere, people still need to be able to go get groceries and things. Most people are not trying to cause inconvenience to others, they are just trying to live their lives.
Yes, they can easily park 3 or more feet out toward the road. It's like they park this way to protect their precious car by leaving it farther from the road, but it screws over pedestrians. As far as utility trailers and campers blocking the full width of the sidewalk, they don't belong there at all, and since they are only there sometimes I can only assume that yes, they have somewhere better to park.
Edit: 3 feet is about 1 meter for folks using sensible measurement units.
