Finally, it should be stressed again that the steering wheel, as well as allowing vehicle control, is the most relevant connection with the tyre contact patch. As a matter of fact, it provides indications about the level of tyre grip and lateral load along corners, or about road surface irregularities and imperfections. One of the main friction effects is to work as a filter, therefore a high level of dynamic friction could filter out the information coming from the wheels, making steering feel poor and deteriorating active safety as the driver is partially isolated from the road.
