You do realize that this is, in fact, very similar to what the people who stumped for "just letting us have bike lanes" have progressed to advocating, right? Totally car-free roads, roads that technically are car-usable but have been rigged so that they won't support normal traffic, various pushes to force (or "nudge" or "encourage") people to ride bikes or take mass transit instead of driving... etc.

And they even helped with convenient tax credits for taking their preferred modes of transportation! (spending tax dollars)
