Russia is in a collapse right now! At the $50+ a barrel who cares if it is in gold or rubles because at the $50+ per barrel Russia is losing money on the oil sold to Europe. At these prices Russia is collapsing. Who cares is it is not in U. S. dollars.
And about the cars what country are you at? When Europe sells car to the U. S. they have to add a lot to pass the U. S. emissions. Where are you from? The rest of the world’s cars do not even have emission control laws that I know of.
