It's amazing to see. The last ten years, the galvanizing project of every european city has been calming cars. I didn't really realize it until I was there the last few summers on vacation, and the difference is night&day with 10 years ago (Brussels, Paris big examples, many smaller ones too). Unreal, a truly positive transformation. It's one of those things, you just can "feel", although maybe hard to explain, I certainly couldn't imagine "the feel" about 10-15 years ago. Hope US cities can marshal that same gumption eventually. This takes top-down courage. It can never resolve bottom up, especially with how fearful and short-sighted americans can be.
