There are many variables to prices, like larger cities, longer commutes (US drivers drive 2x km per year compared to Germany), bigger cars with worse gas mileage - so higher taxes on gas with higher gas prices (like in Germany) would probably kill the US economy.
I do understand that. I am not invalidating the reasons behind it, but it doesn't change the fact it's cheaper. Here we also have trucks, cars etc that take long commutes and thus a very high price will bring the price of transpiration up.
Also I would argue it's maybe better for the US to use smaller cars, since it thus becomes quite cheap to drive. Also this would probably make the roads safer, as bigger cars (mostly) equal unsafer cars (and shit drivers, but that's just my opinion tbh).
