The gas prices in the US are ridiculously cheap compared to the litre price of approx. 1,75€ Germany, let alone some European countries with even higher prices like the Netherlands or Norway.

I have no clue whatsoever why you should panick due to such laughable prices per gallon in your country, which, by the way, literally controls the world's oil prices by its military might and it's epic financial fraud via a completely manipulated $ value.
