Sure, if there's as many people driving Teslas as driving every other car model combined. You've just doubled the amount of traffic on the road and sold as many Teslas as every other kind of car as well in your effort to create a strawman. You're also completely ignoring the fact that Tesla have the opportunity to charge these packs ahead of time, flattening out your tenuously arrived upon peak demand. What a wonderful town you must live in where everyone can afford not only a second car, but a Tesla at that!
In the real world - where of the 80,000 people in your area on average 800 could *afford* a Tesla and of those perhaps 10% would choose to buy one, I don't really see a charging station holding 8 battery packs on hand for all 8 owners in your town as an issue, do you?
