There is a line on the ground so you stop and a giant sign pops up that says CORRECT! You obeyed the rules of the road and did the correct thing.
You did the correct thing, so the Shougun (しょう) shows up to reward you! He holds out a shiny new saber (せい) in his hand, gently taps it onto each of your shoulders, and then hands it to you. It's big, curved and you love it.
