How about a car with no wheels? Here's how (theoretically): an electromagnetic undertray on top of a road system that is fully magnetized in the same polarization as the undertray's side that is facing the road surface (producing magnetic levitation). Now have some plasma thrusters to power the contraption (fueled by liquid hydrogen and powered externally through either microwaves or inductive charging (in the road surface as well! This should be done through resonant inductive coupling). Additionally, air brakes can be employed to help with braking (and turning, similar to the Pagani Huayra), as well as having additional thrusters on the sides to enable sideways movement (as well as having large gimbal capabilities on all thrusters). Additional turning capabilities can be achieved through rear-mounted fins with control surfaces to enable yaw control while at higher speeds (and thus reduce the need for the side thrusters for turning, and instead relegate their operation at high speed to stability).
Congratulations, you've made what is essentially an F-Zero machine!
