HarryMann,
Your reference to power steering, brings forward the "feedback question again". As one that spends time racing cars at speeds that are well above those that normal drivers do, the steering feedback is a very important sensory element in terms of wheel adhesion, or lack of adhesion - the lightness/hardness of the steering is an adhesion indication - if no other sensing mechanism is included in the system, to replace it.
