When people ask me if I would ever consider living off the grid, I sometimes think they’re talking about traffic patterns. I’m used to living in a city where streets are laid out in straightforward north-south, east-west lines. It’s hard to get lost and traffic is predictable. But grid planning is contingent upon physical geography. In a city where the coastline winds around bays and inlets and where mountains slope almost to the water, grids are impossible. Add to that the whole right-hand drive thing and, for a North American visiting Hong Kong, traffic is bewildering.
