I was giving this a bit more thought and joked about the rare metals such as Rhodium and Palladium but it occurred to me that we don't have nearly enough metals that are found in EV batteries like lithium, cobalt, graphite, nickel and copper. Much of these valuable materials are controlled by the likes of China on the global market and if we (US) are going to electrify most cars within the next decade or so, we need to find a solution regarding materials.
So, if that metal asteroid contains some of these desirable materials, it's going to be an all out war! As I said, a movie will be in the works.
