Going off from my previous post about a bathing Vampire Raoul Caroule. All of the WGP racers, running and unrunning are invited to one of the onsens that sponsor Shu Todoroki. The vampire cars are properly invited to avoid awkward

Now I've watched enough bird bath videos on Youtube that multiple birds cram themselves into the same bath and make quite a splash cleaning themselves.

Imagine all of the vampire cars crammed into the same hot spring, cleaning themselves and splashing water all over the room. Some of the vampire cars have developed wings (Raoul, Long Ge and Francesco) and the bath becomes just a little bit more cramped.

Meanwhile, the donor cars are in the hot springs next space over comparing donor bite locations and just chatting about idiosyncrasies of maintaining a vampire donor car relationship. The non donor cars are also just hanging out with the donors, just trying to relax.
