AI Waypoint car

Unity Engine
1

I have a script that its simply an AI with waypoint system that goes from 1 to other waypoint
heres the code:

var waypoint : Transform[];
var speed : float = 10.0;
var rotateSpeed : float = 1.0;
var loop : boolean = true;
var currentWaypoint : int;
var target : Transform;

function Awake(){
	waypoint[0] = transform;
}

function Update(){
	if(currentWaypoint < waypoint.length){
		var target : Vector3 = waypoint[currentWaypoint].position;
		var moveDirection : Vector3 = target-transform.position; 
		var velocity = rigidbody.velocity;

		if(moveDirection.magnitude < 1){
			currentWaypoint++;
		}
		else{
			transform.Translate(moveDirection.normalized * speed * Time.smoothDeltaTime);
		}
	}
	else{
		if(loop){
			currentWaypoint = 0;
		}
		else{
			velocity = Vector3.zero;
		}
	}
	rigidbody.velocity = velocity;
}

but i cant make the AI to rotate towards the next waypoint, so i can change the translate to something more realistic and smoother movement.
Can anyone tell me what i need to make it rotate to the next waypoint :face_with_spiral_eyes:

Something like this may be useful:

//target rotation
Quaternion targetRotation = Quaternion.LookRotation(directionToLook);

//turn smooth
float smallNumber = x * Time.deltaTime;
currentRotation = Quaternion.Slerp(currentRotation, targetRotation , smallNumber);
