Wow. I've travelled to many countries and lived in a few, but I've never been somewhere without sidewalks. I looked at that street view and thought: "that's weird, grassy sidewalks". I had to pan 360 degrees a few times to realise it was people's front gardens, not public space. It feels very alien to me.
Around here, there are laws now that prevent someone from building without providing a sidewalk. Old lots are grandfathered in, I think, but any new development has to also provide a sidewalk.
I suspect it's that way most places, and that's why you find so few without sidewalks. They do exist, though.
