Looks like a different kind of parking spot, note that it’s directly in front of a space where a car isn’t parked. If I had to guess the clear space is an entryway of some kind that is being kept clear by shifing the parking space out (probably just shouldn’t have one at all, but maybe there are parking minimums). If you look to the other side of the street you can see similarly parked cars with walls to their side, so it can’t be intended as a sidewalk there.
are those cars parked all over the sidewalk and ol mate has to walk on the road ?
No, those are parking lots. The car left the road. Also the pedestrian doesn’t look old to me.
What’s that box marking in the center of the frame supposed to mean?
