When a company makes something they rarely are introducing anything new to a market, but are ordering components that are already being manufactured in sufficient quantity in the market to be sourced en masse, and have an assembly company actually build something from these components. Tesla has done some things like some of the assembly in house but they aren't exactly mining the lithium themselves either. They are a customer to many other companies you might never hear about unless you order EV components for an automaker. Tesla's existence is therefore an inevitability of the wider supply chain bringing these components to market. If there were no Tesla, we'd probably still be seeing EVs emerging today, thanks to the expansion of the components markets that make a car like a Tesla or a Chevy Volt possible. Now, Tesla might have lead to these component manufacturers to scale up some knowing they have a buyer, but still, they existed already.
