The homeowner cannot simply cut the street, they have to have permission from the city.
I live next to a Yeshivah, and the bochurim (and sad to say sometimes the rebbeim, too) have blocked my legal driveway “Just a little,” and sometimes halfway over, and even COMPLETELY once (“I’m late for mincha!”). I get that one is late for minyan or has trouble finding a spot, but that is NOT MY PROBLEM. Get to shul or school earlier and park to your heart’s content. DO NOT block my driveway even just a little, because that means I cannot park my own car in front of my own LEGAL driveway, and it is an incredible tircha for me to have to look for another spot all the way down my block (sometimes very late at night, because I work at night sometimes), as I have severe knee problems, and walking (especially while carrying packages) is torture for me. It IS gezel to block someone’s driveway, and you have no idea what nezek you may be causing the homeowner. And this is exponentially worse in the winter, when parking apots are at a premium.
What’s really drinding my gears is when I see someone actually doing this when there is ample parking ALL ALONG THE BOCK, often including the very spot they are parking in, if they would only move back a foot or so. They just thoughtlessly park without actually looking at how close they are to the driveway. I came out to ask a boy to move his car because I ahppened to observe him parking and he was blocking us. He looked at me like I was from Mars and insisted I was mistaken (he was a third over the driveway). When I told him to take a second look, he realized his error and actually drove off further down the block. GRRRRRRRRR!
(I’m really a nice person. Thank you for allowing me to vent).
