I walked a mile to school in outer London in the 90s and it was absolutely fine.

In Bromley (which is also getting the ULEZ extension) the buses go pretty far into the sticks.
Places like Keston, Downe and Biggin Hill have good TFL bus access while being basically rural villages. Seriously, look up Downe on a map. It's in the middle of nowhere.
