Today’s invention is based on the idea that there is a difference between the accelerative and constant velocity regimes of vehicle movement.
We tend to rely on tyred wheels for both -which entails a compromise between maximising drive and minimising rolling resistance.
Instead, imagine a vehicle with a fat, high-grip drive band (yellow) to be used only during acceleration or deceleration, together with very thin-tyred, slim wheels (blue) to be used only when the vehicle is moving along at top speed on a smooth surface.
These two elements would be swapped in or out depending on the position of the accelerator pedal.
