BMW patents shape-shifting steering wheel
WO2020058178 - CHANGEABLE-SHAPE STEERING WHEEL
BMW has filed an international patent application (PCT) for a steering wheel that can change from a circular shape to an oval-type shape. This allows the wheel to take up less space when the vehicle is operating autonomously. When driver intervention is required, the wheel transforms back into a circular shape.

Studies have shown that a visual cue like a steering wheel changing shape results in a faster response for driver intervention than other warning signals like lights or sounds. https://spectrum.ieee.org/cars-that-...-car-needs-you
