There are about 1 billion cars (not counting trucks) in the world, we made just over 72 million cars in 2016 and there are about 3 million EV's as of 2018. So, if you are going to make an impact you better get EV production up to at least 50 million a year. So you need to get a move on to make much difference. Tesla's production heck is nothing compared the the hurdles you must overcome.
However as a retired petroleum engineer, let me tell you why I like EVs and see the money to be made. First, a few start ups are taking oilfield brine and producing lithium. These fine folks are converting a cost center, into a profit center and the loot will fall through to the bottom line! Who owns the mineral rights? Who are you going to get to drill and produce the wells to get lithium brines? You will use multiple effect evaporators in the US to concentrate the brine, you will buy the gas from us, hopefully right at the well head, save you money and makes us more! All plastics in the cars will come from us, battery case, resins, carbon fibers, synthetic rubber, PVC insulation on the wires, epoxies to encapsulate the electronics, the list goes on and on. Ships, almost all freight railroads, and trucks run on fossil fuels to transport the parts to the assemble plants. Also, natural gas continues to increase market share in utility production, so we will charge the batteries for you. Get on the money train, woo, woo!
It has never been about how you get there, it is about making money.
