Epic win

I don't know why people make such misleading videos. Pontevedra has merely done what has long been the default in many European cities, namely that through motor traffic is banned in their historic (often medieval or older) centres (and it's quite a small area in which many streets are very narrow). This is obviously a good thing, though hardly exceptional. It may well be the exception in Spain for all I know, but (larger) Sevilla has also largely filtered its historical centre except for access. Needless to say, both cities, and the aforementioned European cities in general, are far more car-dependent at the moment than they have ever been, and car traffic still plays a major role in all of these places--people use cars to make deliveries to businesses, etc., even in the historic streets, probably at designated times, and there will be major car parks for visitors who then proceed into the historic centre on foot. Just look around Pontevedra on StreetView and you'll see cars almost everywhere outside the small zone affected, and quite a few inside it, too. Again, it's obviously better than before, but not particularly unusual.

Paradoxically, and counter-intuitively, compared to its huge population London actually has less private car traffic than places like Pontevedra. This is because of the immense capacity of public transport, which none of these smaller places, which have all sprawled, can match.
