> Whatever suburb you live in is extremely unusual as far as suburbs go.
I disagree. Every suburb I've ever lived in has had services within walking distance.
> Suburbs are almost defined by the lack of amenities accessible by foot.
Well... If you decide to define suburb by lack of walkable amenities, then of course by definition any place that's walkable isn't a suburb. Tautologically, so I can't argue with that.
But I will argue that this is not actually the definition of suburb!
> There are cities other than New York and SF
Sure but those are the top two densest cities in the US, so worth considering.
> Yes. I absolutely find it safer riding my bike in Manhattan than in the quiet suburb
Interesting. Well that's very different from my experience. Riding a bike in Manhattan is an extreme sport. I did it in my youth along with other risky things but in hindsight maybe a bit too much risk. Riding a bike out here in the quiet suburbs is a pleasure since there's so much less traffic and more space.
