All those books are about race car suspension geometry. When a race car is in a turn, the tires generate higher slip angles (skidding) and throws traditional Ackermann steering theory out the door. But the idea of both front tires turning on different angles like in Ackermann is used in a circle track cars. They use it to manipulate the tire slip angles and have adjustable steering arms for it.

Street cars in normal lawful driving don't have the front end in high slip angles (skidding).

It's described in better detail in Miliken "Race Car Vehicle Dynamic" 1995 pg 128. It terms this street car situation as, Steady-State Low-Speed Cornering Geometry.

Also goes into Ackermann steering geometry on street cars on pg 713 :read2:
