I found something hilarious in the driver manual: the "Animal" section.
It says, "Use caution when you approach or pass someone who is riding, leading, or herding livestock on the highway." Livestock (Mind you, they are not cats or dogs!) on the highway?! Unbelievable. I haven't seen animals except dead cats or birds running on the highway in Japan even though I'm originally from a rural town.
And it goes on, "If you ride, drive, or lead any animal on a road, you must follow the same rules of the road as motorists ..." Gee, you let your animals run on the right, keep traffic lights and speed limits and signal when they make a turn?! That's hilarious to imagine animals carrying frontlights, taillights, hazard lamps and whatever.
