Today’s invention is another new steering wheel.
This consists of a circular disc, bonded to the dashboard so that it can’t turn.
Two flexible handgrips, linked by a bar, clip onto the outer rim of the wheel. The grips would be coded so as to be usable only in one vehicle.
These are wirelessly connected to the steering mechanism of the vehicle so that their rotational position directs the car.
Steering would thus be inertia-free and the wheel, being stationary, could accommodate all manner of extra interfaces.
The driver would remove the grips on leaving the car, making stealing it impossible.
