Are European cities and Chinese cities going car-free? I've heard of some in Europe and china that are.?

In China cars are taking over. It is now dangerous to ride a bike in most main cities and it is getting worse.

Very unlikely that any city is going to go totally car free.

In Europe there are a few cities that have restrictions on entry for cars for the whole city, but that is a charge for most cars and sometimes a ban on some of the most dirty cars.

But most cities have just a small area where there are no cars allowed, just a few streets where people walk.

And in those streets cars and even lorries are allowed in for a few hours each day to get the supplies into the shops.

yes, this is necessary, a lot of cities bigger than 100k people already trying to limit car traffic, at least in city centers. Great idea for me, public transport should have the top priority

As car free as possible.

YES. Most UK cities are anyway

You heared wrong.
