Whilst Ackermann steering is a very easy to understand concept where the wheels turn to follow a radius with the same centre, as below, it only works at very low speeds. Tyre slip is the dynamic that spoils this otherwise ideal at higher speeds, so modern cars use a version by way of compromise.



Taken to the extreme of F1 some cars go as far as using anti-ackermann where the outside wheel turns in more than inner benefitting high speed cornering. Clearly though with a sports car on wide tyres the compromise will lead to tyre scrub on full lock at manoevering speeds.
