Use

pawn Код:

public OnPlayerDisconnect(playerid, reason)
{
    if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
    {
        SetTimerEx("QuitDestroy", 600000, false, "i", GetPlayerVehicleID(playerid));
    }
    return 1;
}

forward QuitDestroy(vehicleid);
public QuitDestroy(vehicleid)
{
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(IsPlayerConnected(i))
        {
            if(GetPlayerVehicleID(i) != vehicleid)
            {
                DestroyVehicle(vehicleid);
            }
        }
    }
}

Should work, just tested it and it did for me.
