When people drive a car, they look at the moving objects around them so quick visual recognition of the position of objects and their expected trajectory is necessary.

So the object's features will need to be used to predict the trajectory, such as the angle the object is facing and their turn signals.

The distance of the object may be determined quickly if there is 3 video cameras pointing at the same direction but can see different distances so the distance is according to which video camera is getting the clear visual.

The videos probably should be low resolution and just 3 colours, red, yellow and green since only these 3 colours have meaning on the road.
