In this chapter, we looked at Smart Car, an AI system specifically for car AI. We discussed why automotive AI is different than most AIs because of the physics involved, and we also saw how to set up a car model, create a path for the car, and add obstacles. We also looked at using Unity's built-in navigation mesh system, instead of using third-party ones such as RAIN, and discussed additional features for car AI and how we can integrate it with another AI system such as RAIN.

In the next two chapters, we will look at how to combine character animations and AI to give them a realistic appearance and learn more about creating complex navigation meshes for different AIs.
