FWIW, I consider bikelane uprising an org/platform that's capturing that sort of latent/kinetic demand you're talking about, which they've been able to take their work to electeds, who in-turn take action on creating new bike lanes, fixing road damage, raising accountability for companies that park in bike lanes, etc. The emotion they work from is discrete anger and frustration, which tends to ignite action from a bunch of folk to make calls to electeds and such. If you can find a way to bring out that raw feeling on top of what I personally feel as nostalgia for the future in what you're building, it can almost definitely lead into some great stuff. Just don't forget about the politics :)
