Resolved Missing parts in understanding of Vector3

Lane change mechanism,I have an algorithm that makes it similar to the one in Subway Surfer and it works. However, as far as I've learned, this code should not work properly because for example, (-2.5,0,0) should be in Vector and let's assume that the target position is 2.5f, so the result (5 ,0,0) but the code works.
And then we multiply moveVector.x by speed, so it should break the code, but it still works.
Despite all this, how can my character switch between -2.5 0 and 2.5 perfectly? How does CharacterController.Move work?

My Code ;
(LANE_DISTANCE = 2.5F BTW)

Code (CSharp):

1. if (desiredLane == 0) //1 Birim sola kay
2.             targetposition += Vector3.left * LANE_DISTANCE;
3.         else if (desiredLane == 2) //1 Birim saga kay
4.             targetposition += Vector3.right * LANE_DISTANCE;
5.  
6.        
7.         //Calculate our move delta
8.         Vector3 moveVector = Vector3.zero;
9.         moveVector.x = (targetposition - transform.position).x * playerSpeed;
10.  
11.         moveVector.z = playerSpeed;
12.  
13.         Vector3 move = new Vector3(moveVector.x, 0,moveVector.z);
14.         controller.Move(move * Time.deltaTime * playerSpeed);

I fixed the problem but i don't know how to close the topic.
My solution was delete lerp code in Camera script
I know I asked question about the vectors system but it thought it was the thing causing jitter problem so the solution may look irrelavant but actually fixed the problem

 

I couldn't figure how to do it

 

Thanks
