Great but more important is how battery prices keep falling. Power density is already high enough that long range versions of the Model 3 can go 400 miles, which, with fast charging available when needed, is enough for the vast majority of auto owners. The problem is that the battery pack that takes makes the cars too expensive to purchase for most people. But in a few more years falling prices will make ev's similar in sticker prices to comparable ice's. That plus much lower operating costs will cause ev sales to skyrocket.
