Curious, have you ever lived for an extensive amount of time in a walkable European city? As a person who was born and raised in suburban East Coast car-hell and then moved to Europe, I would never want to go back. I still want a luxury car for rare drives to the countryside, but I hate it every time I have to go back to North American car-dependent cities, except for the nicer walkable downtowns.
I've given up on "arguing" with people on this thread, but FWIW, I have lived in Berlin and Frankfurt both for extended periods of time (2.5years total). I'll leave it up to you to decide if those are walkable cities or not. I also currently live in NYC, which is, if not walkable, anti-car.
My boys (one with ASD and the other with ADHD) are often extremely loud. When they are, you can hear them clearly from a surprising distance away from my suburban USA home even when they're still in the house.
