pawn Code:

if(RaceBusy == 0x01 || RaceStarted == 1) return SendClientMessage(playerid, RED, "<!> There's a race currently. Wait first till race ends!");

I think it's that. Probably that 0x01 is wrong, unsure though.

pawn Code:

if (strcmp("/startautorace", cmdtext, true, 10) == 0)

Why typing that long if you can simply do:

pawn Code:

if(!strcmp(cmdtext,"/startautorace",true))
