Well it would need to Drive and Fly…
It needs to be able to generate lift (could be through a wing, or a thruster like F-35) and steer in the sky.
It also needs to be able to drive around our roads and also use things like car parks, motorways and narrow little streets.
It would be the job of the engineer to come up with solutions to these problems. For instance.. we could propose foldable wings. Or even inflatable wings.
