I will urge all drivers to be considerate of other road users when approaching yellow box.
Don't use yellow box as your waiting area "while traffic light is red in your favor" as others could be waiting for long to exit to find you are blocking their way. I have numerous cases when trying to exit car park but no one want to give way and when comes your turn then entire box is blocked by taxis/cars (Happen very frequent at Marina bay financial center car park exist).
