"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...."

"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 loo will come with a fan and exhaust pipe to channel odours out of the car.... Waste is collected in a tank that has to be emptied manually. The toilet also features a rotating heating element that evaporates urine and dries other waste. When not in use, the toilet is concealed beneath the seat, making full use of the space inside a car without requiring more room."

BBC News reports.

…I would have thought this to be silliness bit spend some time on any EV website and you quickly discover many Americans are closeted Cannonball runners who wouldn’t think of stopping longer than five minutes to refuel. For this crowd the car seat potty is a dream come true…

When I would go to the farm with my Dad, we just pulled over and went behind a tree.

There would be a market for this in Tesla's new semi trucks. No more Gatoraid bottles! If you've ever spent time on a cleanup gang on the side of the highways (I'm guessing you haven't), you'll know how many bottle of urine get thrown out of trucks.

I personally know of at least one person who would welcome this.

I personally carry one of those hospital urinal jugs in my car, but I tremble to think of a rolling bedpan.

Come drive the all new 2027 Seres Shitboxia!

I just need a convenient way to pee. I plan hikes around toilets and trees :) This time of year the toilets are closed, so trees and bushes it is.

Imagine walking into that showroom.

During the pandemic when public toilets were locked up, I just kept a wide-mouth Hellman's mayonnaise jar in my truck for those times when I absolutely needed to take a Wii. I should have patented it.

I would have gotten around your patent with my patent for a Duke’s mayo jar.

Ready Whip.

I'd rather we just build more Buc-ee's.

Leave it the the Chinese to make cars that are literally shıtboxes.

Do the poop and pee end up on the roadway, like on Russian railroads?

But if you want my pee jar, you'll have to pry it out of my cold, dead hands.

Having been exposed to the noxious fumes from an in cabin loo in a B-52, trust me, if they don’t also offer an oxygen mask, don’t go for this option.

Cool. A San Francisco car. Dried shit on the streets as well as the sidewalks.

I spent 6 weeks on a tour bus. First thing they tell you (if you've never been on a tour bus) is: DO NOT USE THE TOILET for anything other than peeing. NO ONE violates this rule.

Obviously, the shit car should include a robotic arm for ass wiping.
