I dunno if this is rite but wen u look at the sign in the tunnel that says DAY x/2 Me and the bus is coming, the bus CROSSES OVER to the sign (from the left lane to the right lane when looking at the sign closest to bus depot). If the bus was using the day route then it might mean that the bus (DAY) crosses over to ME (the sign) and its the same for the sign on the other side of the tunnel. I have no idea how the clue helps anyone if this is correct but it could be just more evidence that the bus is using the day route and that there is a night route and maybe it doesn't cross over to the signs and just drives through the barriers. Sorry if this theory has already been made.
