What can a hovercraft do, which couldn't be satisfied as well or better by: - Hydroplane ferry (Competitive speeds) - Multirotor ground effect vehicle A hovercraft could come up on land, which might simplify loading and unloading. But I don't think this is enough of an advantage. The weakness of hovercrafts in their earlier heyday was reliability, maintenance, and overall cost. Hydroplane ferries also have higher costs, but there are still some running to this day, so these must not be as high. As air taxis and other electric aircraft start to benefit from economies of scale in the future, multirotor ground effect aircraft (think Ekranoplans) could also benefit. But the other electric aircraft would likely outcompete them, except on a few very high traffic routes. A big advantage air taxis have, is greater flexibility in loading and unloading.
