A hovercar parked on grass
A car that can hover a few meters above the ground, thus avoiding things like potholes and able to go much faster than a groundcar due to lessened friction, and at lower cost in terms of energy than a true aircar. Most hovercars use antigravity plates to lift themselves above the ground, but a few cheaper models for use only in cities use magnets to levitate above magnetic grids embedded in the pavement.
