Drivers

A car's logic (a "Car" class) is controlled only by the car's physics and signals. It also has all functionality necessery to drive a car. Any car (user-controlled or AI-controlled) needs a "driver" to follow road regulations.

For this purpose, there is a special base class called "Driver". Each car should have an instance of this class to be controlled.

A "Driver" class implements the following:

• Search for the road and road's direction.
• Evaluation of the amount of lanes.
• Recognition of the lane, along which a car is moving.

Crossroads logic can also influence the "Driver" class. When a driver enters the crossroads (no matter if it is a user-controlled or AI-controlled driver), it receives the crossroad driving spline and driving priority value. A spline is defined the following ways:

• For user-controlled cars: based on activated turn signals.
• For AI-controlled cars: chosen randomly.

All of the drivers make decisions for further movements based on these splines and driving priority values. Thus, "drivers" act like they do on real roads: they look around, look at other cars and their turn signals, look at stop signals, and look at crosswalks and let pedestrians pass by.
