Call the parking department of your local PD. They will gladly write a ticket to that Teshole. I've seen the same in my 'hood, and it's highly annoying.
Yeah, but I intend to keep living in my house for decades, and sic'ing the cops on a neighbor is a somewhat unpleasant way to introduce oneself, and sometimes a prelude to lengthy feuds.
Since I've never met them, I'm still pondering the best way to address the problem. Cops, anonymous note, signed note, each have their drawbacks. So for the time being, I content myself with passive aggressive whining to third parties.
You’re worried about keeping up appearances with a neighbor you never met? Call the local police it’s their job to sort that out. If your neighbor confronts you deny or avoid the question if it suites you. Respond with “Oh, you were the guy blocking the sidewalk.”
