When we set static toe-in, frictional forces tend to move the tires towards toe-out(zero toe) when we drive down the road(dynamic).Ackerman angles ( built into steering knuckles)create toe-out-on-turns or turning angle. Cars set with static toe-out tend to wander and be "twitchy"




Yes, the ackermann kicks in after the car is in the turn and there is more tire angle. But like jcc mentioned the toe out really helps initial turn in. Most racing sedans (large cars) have a little toe out. The higher caster angle helps it not be so twitchy going straight.

Most road courses and autocross course dont have very long periods were the steering is completely dead on straight.
