It is completely useless for flying cars. It has zero use for getting things into orbit. The only thing that's amazing about the EM Drive, if true, is that it doesn't require a propellant. It's extremely energy intensive, but since energy can be derived from a reactor or solar panels, this is often easy to overcome. In an atmosphere solar panels are drag, and a reactor is completely insane.
