Ah, but then you can't do a quick U-turn. I think ideally you'd queue up to two moves, the second always being a 180 if any, but if you change your mind it clears the queue. E.g. you're going right, you can queue up-left or down-left but if you hit up-left-up you just go up, up-left-right you just go right, etc.
