Being stuck in traffic is terrible, but being stuck in traffic when nature calls can be even worse. Where do you go if you need to go but there’s no rest stop or public toilet in sight? If things go after a newly filed Chinese patent, you go while on the go—without ever leaving your seat. Filed under patent number CN224104011U by Seres Automobile (the company behind the Aito brand), this contraption could help you empty your bowels and traumatize your passengers at the same time.

What you are looking at here is an invention that some may say shouldn’t exist, but here we are, marveling at it. The toilet is mounted on rails and hidden beneath the seat until it’s time for that important meeting. It can be deployed manually or via voice command, and you can make your own jokes as to what words might be used to make the portable potty appear. The patent mentions “Start up toilet function” as the official phrase to be used in case you need to know.

Anyone who has ever driven around the back of PITX knows that plenty of people are already going number one while on the road (and then chuck the bottles out of the window), so the idea of a seat-based CR isn’t actually that crazy when you think about it. The awkwardness is more based around the thought of doing it while others are in the car at the same time. If it’s just the driver on his own with no witnesses, then this might even work, especially as the proposed system has odor control built in and comes complete with a waste collection tank and a mechanism to evaporate certain fluids. It can even dry out solid waste to reduce bacteria, and it funnels smells right out of the car—presumably straight onto the faces of people unlucky enough to be nearby.

Seres hasn’t mentioned if this will end up in any particular Aito model of theirs, and it does seem like a typical case of great idea in theory (although we’re not so sure about it in practice). The Chinese patent is also not exactly new. Mobile toilets are an everyday feature in recreational vehicles, and even some artista vans have them, but they are commonly installed in their own little cubicles. One patent filed in the US some years ago already got rid of that kind of setup, and instead placed the throne in the back bench of a normal car, where a privacy curtain was supposed to shield the remaining passengers from the type of business no man should have to witness during a road trip.

All of these inventions beg the question why you would go through so much trouble and not just pull over somewhere, even if it means an impromptu al fresco meeting with frogs at the side of the highway. The whole setup seems a bit unsafe for use while driving, and it has “interesting insurance claim” written all over it when it inevitably goes wrong.
