The number of people buying the high end Tesla cars is and will be exceedingly small and no concern for the grid operators. The number of people who will buy a second probably much larger pack for their home (so they can still charge after a number of cloudy days) will also be very small. So that leaves everyman charging slow in the least expensive way - probably from the grid, and spending those dollars saved on more obvious needs than fast charging.
Of course at some point battery packs will be come cheap enough that the lowly like myself may consider it. This is not near term however. Solar at home is good if you have nice treeless southern exposure and some acreage in that direction. A lot of people will be plugging in some other way, charging stations make sense for them. I expect to see big solar arrays and batteries for fast charging at a price, but not a very high price.
