A single billion is an obscene amount of money for an individual, I can’t fathom how anyone can be worth/earn a billion in a couple of years.

They actually gave them a loophole doing the exact opposite, vehicles with a bigger footprint had less strict mpg requirements.

This was written in 2011:

CAFE standards create profit incentive for larger vehicles
The current Corporate Average Fuel Economy standards create a financial incentive for auto companies to make bigger vehicles that are allowed to meet lower targets, according to a new University of Michigan study.
…
The loophole is the formula for setting mile-per-gallon targets. The standards, which actually depend on the sizes of vehicles automakers produce, are expected to require that firms boost average fuel economy to 35.5 mpg by 2016 and 54.5 mpg by 2025. Those oft-cited numbers are averages. In reality, each car company must meet a different standard each year determined by the literal “footprints” of the vehicles it makes. A vehicle’s footprint is its track width times its wheelbase.
According to the study, the sales-weighted average vehicle size in 2014 could increase by 1 to 16 square feet

Apparently decreasing sales, but half a million Buicks sold in 2023, plus the whole: “GM China sales decreased nine percent to 2,098,980 units during the complete 2023 calendar year. Sales decreased at all five brands marketed by GM in the Asian country, including Buick, Chevrolet, Cadillac, Baojun and Wuling.”

At that scale, it would be extremely embarrassing if GM can’t stay competitive & profitable.

So your composition is HVAC, plumbing, electrical, and Swede?

You are correct, every dishwasher I saw in Europe has had a salt compartmebt for softening. None of the US ones I’ve come across have one. Those do on the other hand have a hot water inlet next to the cold inlet, which is kinda neat I guess.

Everyone else is saying vinegar, which will certainly work.
But if you’re like me and cannot stand the stench of vinegar, then I recommend citric acid. 2 tablespoons to a liter of water is a good place to start, but you can most likely find dosage specific to your machine with some googling.
Also, you can get ~2kg of citric acid for 15~25 $or€. I use it to descale everything from coffee contraptions, to shower heads; and a big bag of it lasts us 1½ years. Our water is fairly hard too, about 160 TDS.
