You have a cross for a drunkard's car, to place on its dashboard. Drunkards should not drive, and when you put on a cross, it prevents the car from starting!

You have a lot of crosses to place on drunkard cars, so you get your cyborg (さい) to do it for you. The cyborg doesn't need sleep, so it can patrol the streets 24/7 for the sake of public safety. What a saintly cyborg.
