     if (Input.GetKey(rightKey))
     {
         rigidbody2D.velocity.x = speed;
     }
     else if (Input.GetKey(leftKey))
     {
         rigidbody2D.velocity.x = speed *-1;
     }
     else
     {
         rigidbody2D.velocity.x = 0;
     }
 }

but i can`t move this car left and right with A and D or any buttons .....

Maybe you can use

 Input.GetTouch(0).position;

and then check for whether X is on the left/right side of the screen ?

 void Update() 
 {
   if (Input.touchCount > 0)
   {
           if (Input.GetTouch(0).position.x < halfX)
           {
             // Move left.
           } else if (Input.GetTouch(0).position.x > halfX)
           {
             // Move right
           }  else 
           {
             // reset movement.
           }
   } else 
   {
     // reset movement.
   }
 }

$$anonymous$$y best guess is you have some errors in the brackets. Also, (since you wrote your code snippet in javascript) this code is in C# you may want to convert it to javascript.

From the error line number (1,6) i think you're missing

using UnityEngine;

 {
   if (Input.touchCount > 0)
   {
           if (Input.GetTouch(0).position.x < 2.5)
           {
             rigidbody2D.velocity.x = -10;
             
           } else if (Input.GetTouch(0).position.y > 2.5)
           {
             rigidbody2D.velocity.x = 10;
           }  else 
           {

position The position of the touch in pixel coordinates.

from the unity Documentation. I think that halfX should be half of the screen width ( in pixels ) ex. if the width is 400 it should be 200.

also the second check is wrong.

 else if (Input.GetTouch(0).position.y > 2.5)

why check for y value? Is this desired?
