You seem to mistake this with public mass transit as it is now in some parts, whereas the problems you describe don't even exist in other parts. Depends on cult

You seem to mistake this with public mass transit as it is now in some parts, whereas the problems you describe don't even exist in other parts. Depends on culture, enforcement, whatever. Besides that, why not compare this with rental cars? You'd probably order this by app on you smart gadget. Car from pool of (just recently) free cars arrives. You check it, see/feel/smell/tell something icky, check NOPE! on the app, signal for next car. Meanwhile former renter gets negative points for leaving dirty car, points accumulate, raise dirty renters rates accordingly. Nudge, nudge, problem solved...
