Hahah, Class!

Okay, well here is what I use, all it does it allows enemies to follow a waypoint one after another

var waypoint : Transform[]; static var speed : float = 5; private var currentWaypoint : int;

 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)
             velocity = moveDirection.normalized*speed;

     rigidbody.velocity = velocity;

This goes in your enemy!

This code below, goes into a game empty:

// Draw the waypoint pickable gizmo
function OnDrawGizmos () {
    Gizmos.DrawIcon (transform.position, "Waypoint.tif");

Now with that, what you do is create a game empty on your scene, then drag that script onto with. Where ever this point is, the enemy will walk to it. You can have more than one waypoint. Just means the enemy will walk to one waypoint, then to the other

BTW -- the Waypoint.tif is just an image that is placed over the top of your waypoint - so you can see it. To get yours working, create a file in your project called 'Gizmos', then place a simple small image in there, then call it Waypoint.tif

The "rigidbody.velocity = velocity;" line needs to go inside the closing brace } above it -- otherwise velocity is not defined. Normally wouldn't comment on something so obvious, but there is an incorrect answer that could misslead folks -- will comment on that also.

There are tons of different ways.

The solution above may work for you. Personally I prefer using a spline path (Bezier curves faded together, basically; the forum has a few implementations available) which represents the optimal drive line. You then have each car attempt to match their rotation to the path's direction at the closest point to the car.

Console says (unknown identifier: "velocity") Is says this for last line of code on the first script (rigidbidy.velocity = velocity;)

I deleted that last line but when I ran the game the cylinder that had the script attached to it didn't move

just replace rigidbody.velocity = velocity;

in rigidbody.velocity = speed;

This is incorrect, please see the comment I left on that answer -- line just needs to move up a bit. If you used speed, object would move at the same speed, same direction/etc.. would not head towards waypoint at all.
