and probably the most expensive, I see them going in circles all day long in my neighborhood, fuel alone must have cost a fortune
7 USD is 5.99 EUR. That would be 1.58 EUR/liter. They aren't just approaching that, that is pretty much exactly the current price for gasoline with 10% Ethanol added in several German cities that I checked, with some fuel stations cheaper and some more expensive.
If you need E5 (older cars can't handle E10), you'll pay more than that.
