Think about a pedestrian/cyclist being hit by a car: the person with the lowest carbon footprint, space use, noise and pollution production hit by a high carbon, space-guzzling, noisy and polluting box of metal. 

Roads are for **people**, not for cars - cars have their uses, but that does not imply that the whole system should be built to satisfy their merest whim.

So well done Wales for making 20mph the default speed limit in residential/built-up areas.

 @33b0a4fd Well, yeah, but that works a lot better in places where the roads descend from ancient footpaths.

But in cities built around cars, it would just be a nightmare.
