I disagree about Kuala Lumpur. Maybe it depends on the area, but IME the walkability is great. Public transport is superb, lots of zebra crossings and foot paths, drivers are considerate. I see lots of people walking everywhere. Even at night, as the city feels really safe.
It's been six years since I was there, so things may have changed in the meantime, but back then I've explored central KL on foot for a few days, and did not find that particularly enjoyable. Public transport is indeed great, but as for actually walking... taking kilometer-long detours to cross some urban motorway, being stuck for five minutes at a pedestrian traffic light, sidewalks being constantly interrupted by driveways or switching to the other side of the road... all perfectly normal. This depends on the area too, of course -- I found Putrajaya pretty nice, for example, but also not representative.
