this might work:

PHP код:

public OnPlayerEnterVehicle(playerid,vehicleid,ispassenger)
{
    if(vehicleid == PrivateVehicle[PV][PrivateVehicleId]) 
    {
           if(Player[playerid][PlayerName] != PrivateVehicle[PV][PrivateVehicleOwner])
           {
                   if(!ispassenger)
                   {
                           RemovePlayerFromVehicle(playerid);
                   }
            }
    }
    return 1;
}
