HN draws in a large urban audience. A small, but vocal subset of urbanites absolutely hate car transportation and suburbia. It's a fast growing subculture with many adherents. They favor bike and rail transportation, "complete streets", and removal of surface parking lots.
The /r/fuckcars subreddit, for example, would absolutely turn this thread into an anti-car talking point.
I personally don’t hate cars, but I hate that we let them park anywhere for basically free. If we built more high-volume garages and then banned street parking in city cores, our sidewalk cafes and restaurant culture would improve dramatically. Remove parking, expand the sidewalks.
