Why are there tiled sidewalks in Kuala Lumpur?

Kuala Lumpur is in peninsular Malaysia and experiences heavy rainfall almost all year round thanks to 2 different monsoons which hit the peninsula from the east and west sides. Given the hot, humid, and wet climate one really has to ask oneself…WHY ARE ALL THE SIDEWALKS IN KUALA LUMPUR TILED?? When I say tiled I mean tiled as in bathroom tiles which are extremely slippery when wet. Add to that the fact that it’s really hot in KL and everyone wears sandals and flipflops I cannot fathom whose idea it was to tile the entire city. There must be so many twisted ankles and broken hips from people slipping and falling when it rains. To the guy who ordered the city be tiled, you suck!
