I get that this is obnoxious, but I would probably make the same mistake. It’s just a habit to pull my car up to the “front” of a parking spot. Most curb parking that I’m familiar with includes spacing for car overhang that is apart from the sidewalk, so this seems like understandably thoughtless parking, but it’s also really poor parking/sidewalk design. It’s much easier to pull fully into a spot then it is to try to guess how far back from the front to park to leave enough space for the sidewalk but also not having your ass hanging out in the way of through traffic.
