The original Hyperloop design relied on an air cushion, but nobody claimed that it was flying. A seaplane is similarly not considered a flying car, and is unlikely to be efficient. Nor is a hydroplane. As for cities with traffic jams, expecting governments that don't get enough in taxes to improve infrastructure to solve that by expecting the citizens to pay tremendous amounts for flying cars is unreasonable.
