That's a very different claim from "solving a problem that doesn't exist." And the problem with all of your "how about" whatevers is that we've seen for decades now that many cities are not solving these problems, and there's very little sign that that's going to change any time soon. And not simply because people are stubborn, but because tons of actual practical challenges are intertwined with the political gridlock.

I don't know if you've noticed, but the planet is falling apart right now. We don't have the luxury of waiting for a thousand broken city governments to get their shit together and solve their transportation problems. Even if things like this are only intermediate solutions, if they help, that's a good thing.
