Moscow, Russia, paves many pedestrian sidewalks with stone (or faux stone?) tiles. It is a nightmare in winter when it is slippery like hell, and in wet demi-season, water gets under tiles and squirts up when you step on them. It also looks more like cobblestone paving after 1-2 years because they cannot figure out how to prevent individual tiles from skewing and sinking.
