Most NYC residents don't have walkable commutes, especially those living in middle or lower income neighborhoods that are generally further from the city center. The city is too large, and not particularly pedestrian friendly in the outer boroughs. FWIW Biking has become more viable in recent years, with a good amount of bike lane coverage even in the outer boroughs, but that's still not viable for the less physically able, and I don't know if it's actually cheaper than public transit once you factor in bike equipment/maintenance costs and increased travel times. Also the weather gets fairly extreme in both the summer and winter. Taxing rideshares sounds like a good idea, though I'm sure Uber would fight like hell against it.
