problem with multiple raycasting from multiple gameobjects

hi to all,sorry if am wrong.iam trying to raycast from different gameobjects dynamically using forloop.sorry if am trying in a wrongway.please help me. my scenario is very simple that i need to check whether there is any game object infront of any car(gameobject from which raycast is produced).here, i have more than 5 cars.so i need to raycast from those 5cars and have to capture the hitpoints,here is my attempt of producing multiple raycast from multiple gameobject.plz help me.thanks in advance

 Ray[] RaysArr;

RaycastHit[] hitArray;

 public Gameobject[] cars;
 
 void start()
 {
 cars= new GameObject[5]
 for(int i =0; i<cars.Length;i++)
         {
             cars[i]= GameObject.Find("cars_0"+i);
             //hitArray[i] = new RaycastHit( );
             
         }
 RaysArr = new Ray[cars.Length];
 hitArray = new RaycastHit[cars.Length];
 //i dont know how to declare raycasthit array
 
 }
 void update()
 {
 
 for(int i =0;i<cars.Length;i++)
             {
             RaysArr[i]= new Ray(cars[i].transform.position,cars[i].transform.forward);
                 if(Physics.Raycast(RaysArr[i],out hitarry[i] ,10f))
                     {
                     dosomething();//if hits
                     }
                 else
                     {
                     dosomething();//if doesnt hits
                         
                     }
             
             }
