My first car was a 96 f-150 the previous owner named "Maurice" I didn't change it cause it supposed to be bad luck. Then I had a 2001 Pontiac grand am I called "Jaun claude" which I was rather proud of. My current one is just "V" cause it's a Ford Fusion Hybrid and the engine looks like it came out of cyberpunk.
I would assume that includes stuff like toilets,baths,showers,dishes and hand washing etc as fresh water uses. Either that or Germans are the ultimate hydrohommie.
