{
	if (PRESSED(KEY_SUBMISSION))
	{
        new Float:x, Float:y, Float:z;
        if(IsPlayerInAnyVehicle(playerid))
        {
			GetVehicleVelocity(vehicle,x,y,z);
            SetVehicleVelocity(vehicle,x,y,z+2);
		}
		else
		{
			GetPlayerVelocity(playerid, x, y, z);
            SetPlayerVelocity(playerid, x, y, z + 2.0);
        }
	}
	return 1;
