What if I told you that having absolutely no community third spaces is a result of car dependency?
Ever heard people complain that it's impossible to just meet new people in real life because everyone everywhere is busy? It's because we don't have third spaces anymore, and one really big reason for that is car dependency. People really don't like to drive, for the most part, and they're generally not going to go drive to hang out somewhere; it becomes both dangerous and a special pain in the ass if alcohol enters the equation, as it does for many (but not all) third spaces. In short, if people go to a third space, it's usually going to be one inside their own hyper local community or they won't bother. These are all generalities, of course; miss me with anecdotal exceptions. Well, we keep our cities badly zoned and low density so that you don't really have hyper local third spaces, you just get weird, semi-local, sanitized big box "third spaces" (massive sarcasm quotes) like Chili's or Starbucks that don't actually fill that role. They just want you to spend money and get out, there's no actual tie to the community.
Having an outdoors that's so utterly lifeless and hostile to anything that's not a car that kids "hang out" on social media is neither normal nor desirable, unless you're a tech exec, I guess.
