I see this a lot too. Based on where I live, I’ve assumed it’s bc there are too many people living in the house and they need some peace and quiet and/or talk on the phone in private. It’s common to see 6+ cars in front of 3 bedroom houses here, housing prices being what they are.
Just like there’s a machine that removes/places his helmet, his toilet has machinery that removes his codpiece and pulls down his pants for him. It’s also equipped with a full-service bidet.
