when oil was over $100 a bbl, it was looking bright for electric vehicles, maybe.  Not so much today.  Maybe if the cells could be made for a fraction of the price they cost today it would usher in an era of big numbers of EV sales ... but they already make the cells as cheaply as possible in china yet the EVs still cost twice as much as an equivalent econobox.  And no way Musk can make the cells in Nevada for cheaper than China.  I really want an EV, but I will not buy one.  Hoever if EVs are going to blossom, it will be in China where the govt has dictatorial powers to make people buy them (they did this with ICE scooter bands and motor bike bans, leading to the explosion of ebike sales)
