As someone in the UK, I already live within a 15 minute walk of most of these.
Is it really that bad over there? If you're not within a quick walk to the shops, or the doctors, or school, tram and bus stops, opticians, dentists, etc, how do you and the kids get anything done?
Who would intentionally move somewhere like that? The first thing we do when looking at moving to a new place is see what services are within walking distance, to get an idea for how worth it living there would be.
If you've got to walk 30+ minutes just to get to the shops? That's an arse ache you don't want.
