Vehicle exit rotation bug / random vehicle explosions bug.

hello, im having problems with player rotations and random vehicle explisons #pragma strict import UnityStandardAssets.CrossPlatformInput;

 var masinoj = false;
 var peskom = true;
 var triggeris = false;
 var zaidejas : Transform;
 var masina : GameObject;
 var taskas : Transform;
 var crashas : AudioSource;
 var smarkei : AudioClip[];
 var silpnai : AudioClip[]; 
 var Ugnys : GameObject[]; 
 var Dumai : GameObject;
 var Sprogimas : GameObject;
 var Sudegesmasina : GameObject;
 var Damage : int;
 
 function Update() {
 if(Damage < 11){
  for(var i = 0;i<Ugnys.Length;i++){
    Ugnys[i].SetActive(true);
    
  }
 }
 if(Damage < 31){
 Dumai.SetActive(true);
 }
 if(Damage < 1){
 masinoj = false;
 zaidejas.transform.rotation = Quaternion(0,0,0,0);
 Sprogimas.SetActive(true);
 Instantiate(Sudegesmasina, transform.position, transform.rotation);
 zaidejas.transform.rotation = Quaternion(0,0,0,0);
 zaidejas.transform.localRotation = Quaternion(0,0,0,0);
 Destroy(gameObject);
 }
 if(triggeris){
 if (CrossPlatformInputManager.GetButtonDown("Enter"))
          masinoj = !masinoj;
 }
 if(triggeris == false){
 masinoj = false;
 }
  
     if(masinoj){
  
           zaidejas.gameObject.SetActive (false);
           zaidejas.parent = taskas.transform;
           zaidejas.transform.localPosition = Vector3(-0.25,0.25,0);
           zaidejas.transform.localRotation = Quaternion(0,0,0,0);
           taskas.parent = masina.transform;
           taskas.transform.localPosition = Vector3(-0.25,0.25,0);
           (masina.GetComponent("CarUserControl") as UnityStandardAssets.Vehicles.Car.CarUserControl).enabled = true;
  
     }
     else{
           zaidejas.gameObject.SetActive (true);
           zaidejas.transform.parent = null;
           (masina.GetComponent("CarUserControl") as UnityStandardAssets.Vehicles.Car.CarUserControl).enabled = false;
      }
 }
 
 function OnCollisionEnter(collision: Collision) {
     if (collision.relativeVelocity.magnitude < 14 && collision.relativeVelocity.magnitude > 10){
          Damage = Damage-5;
         crashas.Stop();
         crashas.PlayOneShot(silpnai[Random.Range(0,silpnai.Length)]);
     }
     else if (collision.relativeVelocity.magnitude > 15){
          Damage = Damage-10;
         crashas.Stop();
         crashas.PlayOneShot(smarkei[Random.Range(0,smarkei.Length)]);
     }
 }
 
 
 function OnTriggerEnter(collider : Collider){
       if(collider.tag == "Player")
       {
           triggeris = true;
       }
 }
        
  function OnTriggerExit(collider : Collider){
       if(collider.tag == "Player")
       {
           triggeris = false;
       }
 }

1. Masinoj means inside car

2. peskom means on foot

3. triggeris trigger

4. zaidejas - player

5. Masina - car

6. ttaskas - exit point

7. crashas - crash sound audio source

8. smarkei - heavy crash array of sounds

9. silpnai - light crash array of sounds

10. ugnys - array of fire effects

11. dumai - smoke

12. sprogimas - explision effect

13. sudegesmasina - broken car burnt prefab

14. damage - damage points

images to be clearer

^ exploding

^ bad player rotation

So i need help to what to do to get player standing on foot when he exits the vehicles , and whats the thing that some cars upon enter does explode and play crash sounds very much randomly. Thanks for help
