I've run large bike lane/car-free streets campaigns before [1] and have talked with a bunch of activists from groups all over the country, so I have a good deal of experience here.

You're right that these problems are political—in fact, they're entirely political!—but the reason they're so political is because there's no existing platform for capturing latent + kinetic demand, so electeds (even the ones who want better streets—we've heard from many of them on Twitter) have absolutely no idea how much political support they have—and they need that support to take bold action. We're solving that problem!
