Is is not the acheivement of a dramatic steering angle thats necessary?
Absoultely agree that exact ackermann angles are not what most modern road cars use, far more relevant to low speed saving of tyres than performance, in fact in some cases tyre dynamics can actually lead to the use of NEGATIVE ackermann on certain types of car.
