Ever been busting for the toilet whilst in the car?

[Konovalov]

I'm sure everyone has experienced at least once in their life that time when nature calls while driving your car on a long journey or when stuck in a city or motorway traffic jam. No surprise then that the Japanese have come up with a brilliant solution in the shape of the revolutionary car toilet.

From the article:

Drivers stranded by tectonic movements or stuck in traffic simply assemble the cardboard toilet bowl, fit a water-absorbent sheet inside and draw round the curtain.

Hmmm, don't leave home without it?
