Run "example.py" to see the sim work. There are four different vehicle models.

• One dimensional lookup: Simple diamond shaped g-g diagram where longitudinal acceleration is a function of lateral acceleration.
• Two dimensional lookup: Two dimensional g-g diagram where longitudinal acceleration is a function of lateral acceleration and speed.
• Aero Mass Tire: Simple physical model with quadratic aerodynamic downforce and drag, a mass, and a load sensitive tire.
• General Model: A much more complicated model with suspension stiffnesses, wheels speeds. Much slower because it must optimize the vehicle state at every step.

Run "example_tire" to see the tire model used.

• The "Aero Mass Tire" model uses the load sensitivity behaviour from this model.
• The "General" model uses the force vs slip shape and the friction ellipse.
