The steering of wheeled vehicles is a complex subject in automobile design. While some real-life issues are of lesser importance in Lego models because of their limited size and weight, it still pays to understand the principles at play.
in this chapter, we're going to lean how to buid typical LEGO steering systems as well as how to implement optional features of steering geometry and multi-axle steering.
Note that this chapter omits vehicles with fewer than four wheels. Steering bikes or trikes is elementary, so we are moving straight to where the real challenges begin.
