Air-taxi
From Jenny Everywhere Wiki
In one universe, air-taxis were common in the futuristic New York City in which the Magician from Mars operated. They were flying spherical vehicles with a clear top half and a red bottom half. They had a separate compartment for the driver at the front.
Though capable of flying by herself, the Magician called an air-taxi for herself and a man she saved from jumping off the Manhattan Bridge, so that he could tell her about his woes privately as they flew. (COMIC: On Earth)
