The capability of Sentient’s Vehicle Motion Control exceeds the ability of human drivers. To achieve this, the angular speed of the steering wheel need to be greater than 1500 °/s. Using a car with a steering wheel moving that fast would be unsafe, e.g. sticking a finger into the wheel could lead to bone fractures.
Also, in Autonomous Vehicle Motion Control, you would prefer to keep the steering wheel still to avoid any annoying motions.
Sentient’s steer-by-wire has the unique combination of disturbance rejection and premium steering feel and it has been in production since 2013.
