They want to somehow have every single person in a 3 block radius park on the perimeter of that area? And this is somehow supposed to make things better?
I also have zero interest in walking 2 blocks to my car when I need it, nor do I want to carry my items that far from my car.
I especially like: "or reducing the number of parking spaces or the number of traffic lanes, for example—actions that might catalyze bigger, more permanent changes in the future."
Yes, let's make people miserable now, because it might possibly make some change later.
The concept of first make things better seems to have escaped them.
I'm really tired of anti-car advocates that have just a single idea: Make people too miserable to use a car, and maybe then there will be less cars.
Making people miserable is not a viable strategy.
