"The suburbs" is such a broad category that it's practically useless. Houston suburbs, for instance, are vastly different than Chicago suburbs in terms of walkability, character, and access to nature. Even suburbs in the same metro are vastly different in experience.
Personally, I prefer to take my car to the shop because I don't want to carry a car load of stuff home. And Central Park is something I like to visit, but I wouldn't send a young child to play there by themselves.
