There's no firm commitment to offering a VTOL choice, although Holden suggests it might happen within a decade. As it stands, any initial offering would be limited by modern technology and city layouts: you'd need piloted vehicles, and the combination of loud engines with limited landing areas would dictate just where these aircraft could touch down. The big breakthrough would come with autonomous, quiet (likely electric) vehicles that could fly almost anywhere. You could get a lift to a rooftop in the heart of downtown, for instance.

And it's not as if either Uber or the industry are standing still. Remember how Uber recently teamed up with Airbus? Well, Airbus has been researching autonomous air taxis -- it's not a stretch to imagine a future collaboration where Uber uses those taxis to shuttle customers back and forth. While four-wheeled ridesharing isn't going away any time soon, it probably won't be your only choice at some point in the future.
