Given whatever size of garage I have, being somewhere I can live without a car gives me more garage space, regardless of whether it's a suburb. If I want to maximize garage space given my choice of a car-free lifestyle, I would probably move to a suburb with a good train station, not one where "only 20 minutes' drive to downtown" is seen as the selling point. Those are subtly different kinds of places, in my experience, where most people are going to fill their garage space with cars.
The antagonism is from effectively calling them immature (and thus implying that their opinion is coming from a place of naivety) and placing yourself above them. This is a pretty standard insult that people use to try to be persuasive.
I suppose you could say that posting that insult itself is so immature that readers should recognize it as a joke, but I suggest that you should try to stay away from sarcasm when posting in online forums. It can be quite difficult to detect the sarcasm of a bunch of people you don't know.
I could end my post by sarcastically saying "don't worry, you'll learn what a joke is when you grow up", but hopefully you can imagine how some people would take that as a genuine insult rather than a joke. Though it would be punchier ending.
Like you did by downvoting?
Are you young? Because this comment shouldn't be offensive unless you're harboring doubt about immature decisions you've made. For everyone else, it's a tongue in cheek poke at the bad decisions I made when I was younger. Statistically, people tend to leave the city when they get older. If you're insulted by that, you probably still belong in the city.
Maybe you should look inward instead of downvoting, or offering explanations that presume a lesser understanding in your audience.
Looking up to experience isn't a bad thing. It shows maturity. How's that for a punchy finish?
