Simple Driving Game Physics - How To Steer A Car Accurately
Accurate steering for a car, bus, or any vehicle with two axles using the simple Ackermann steering model. This ensures that you won't get weird side slippage when you're driving. And is an important foundation for things like self driving A.I. games.
The whole point of Ackermann steering is that the front wheels are turned at different angles, which ensures that every wheel is rotating around the same center point when the car turns. However each while is rotating on a slightly different radius.
Prior to steering geometry like this, if you just had the wheels turn at the same angle, they would be forced to slip sideways on the ground, which would put non-desirable force on the wheel attachments, and tend to break things.
I based this on this tutorial

which I found from Ras Maxim's youtube video
