Ackermann Angle

A point to note is when you turn your car your wheels don’t actually point in an identical angle if they did the car would be hard to turn and difficult to control.

This is because the car has to follow two different curves to go around a simple bend.

 So the steering system must accommodate the severity of the bend and react so both wheels are making the correct arc, permitting the cabin of the vehicle to go around the bend safely and comfortably.

For those technically inclined it is called the “Ackermann angle”
