I didn't know such mentality exist in M'sia. Thought that the 4 working days/week proposed by workers unions in some European countries are dy stretching it.
That's a good idea, if the pavements/sidewalks are constructed and maintained properly, but based on my experience driving around KL city, I sometimes see them badly maintained and there are roads where you'll see none at all, forcing you to cycle on the road.

Then you also have to factor in the rain.
