I don't know if this belongs to Meta but I'll post it here.

I watched this interesting startup video.

The article is about Paris banning cars in a part of the city. The author says: "Brussels, Sao Paulo, and the English city of Bristol have launched similar campaigns in the past".

Now, for example here in Italy we started doing that 42 years ago. We keep doing that every year in many many cities including the big ones like Milan, Rome or Turin.

So Paris is not an exception.

What do you think of these kind of events? Do you think they're useful or not? Does your city take part to them?
