Chinese carmaker Seres has been granted a patent for what it calls an "in-vehicle toilet" that slides under a passenger's seat for visits to the loo while on the road. The feature is meant to "satisfy users' toilet needs on long journeys, while camping or while staying in the car", engineers wrote in Seres' patent filing in China on 10 April. Seres, based in the south-west city of Chongqing, has not announced any cars that have toilets and it is uncertain if any will be made. Chinese electric vehicles have become increasingly packed with unconventional features, like built-in massage seats, karaoke systems and a fridge, to stand out in a highly competitive market. The patent filing shows Seres' plans for an onboard toilet that slides out from the bottom of a passenger's seat with a push or through voice-activated commands. The loo will come with a fan and exhaust pipe to channel odours out of the car. In-vehicle toilets are rare - mostly found in long-distance coaches - but are not unheard of in cars. Most of the company's cars are sold in mainland China, though Seres has also expanded to Europe, the Middle East and Africa.
