if you want a normal Demolition derby then just set the interior to 15 and put the player at x, y, z coords... maybe you can use this:
paste this anywhere under your Command:

pawn Код:

SetPlayerPos(playerid, -1398.103515,937.631164,1036.479125);
SetPlayerVirtualWorld(playerid, 15);
SetPlayerInterior(playerid, 15);

hope i helped you out with your derby cmd
