As reusable rockets were impossible... I don't think it would be easy, but completely doable and one way to go to reduce problems in big cities, especially the capsule-esque bus... Both public and private transport with the same network, it can be good! Especially if combined with autonomous drive from/to the spot and tunnels' lifts. I would definitely be glad to work on a project like this!
