The idea that you could buy a house in an area that is not at all walkable is a frightening thought. What has this world come to if we lives in neighbourhoods where we can't easily walk (or there's nothing to walk to...).
I think if you showed this thread to someone living 100 years ago, they'd probably think the human race was doomed.
Luckily no one living 100 years ago has access to the Internet.
