Wrong, You should create the speed meter when a player enters the vehicle, but showing it when checking if he's driver or passenger if you want, At OnPlayerStateChange:

pawn Код:

if(newstate == PLAYER_STATE_DRIVE || PLAYER_STATE_PASSENGER)
{
             TextDrawShowForPlayer(playerid, sidisplay[playerid]);
}
else
{
             TextDrawHideForPlayer(playerid, sidisplay[playerid]);
}
return 1;

and OnPlayerExitVehicle, Hide it
