pawn Код:

new s[14];

pawn Код:

s[0] = AddStaticVehicle(415,2402.4631,-1446.6404,23.6110,270.3815,36,1);
    s[1] = AddStaticVehicle(415,2402.0166,-1442.0786,23.6080,270.4241,40,1);
    s[2] = ....

You also need a function which checks if vehicle is occupied.

pawn Код:

public IsVehicleOccupied(vehicleid)
{
    for(new i=0;i<MAX_PLAYERS;i++)
    {
        if(IsPlayerInVehicle(i,vehicleid)) return 1;
    }
    return 0;
}

I don't think you can put player in vehicle OnPlayerConnect, but I suggest you to do that under OnPlayerSpawn.

pawn Код:

public OnPlayerSpawn(playerid)
{
    for(new i=0; i<14; i++)
    {
        if(!IsPlayerInAnyVehicle(playerid))
        {
            if(!IsVehicleOccupied(s[i]))
            {
                PutPlayerInVehicle(playerid, s[i], 0);
            }
        }
    }
    //other code
}
