Rob - You make some great contributions to this thread and the forum in general; your thesis here is one I (most understandably, I'm sure) cannot but vehemently disagree with, to the point of having to break my summer time-off and respond.
First, as coming from someone from the LA area, it absolutely reverberates of an "I've got mine, you don't matter" attitude. Quite unpleasant.
Second, because I agree with one of your points: low-hanging fruit should be picked. And there is such a great cornucopia of available sales....in unharvested territories... that the cost/reward benefits for Tesla argue for their continued expansion into such areas, even if at the price of letting established regions coast for a period. For Tesla to improve their presence in Neroden-country like upstate NY, or for less-dense NoAm sites like the midwest or - horrors - Anchorage (as proxy for Alaska - we're used to that) - is for them to absolutely, positively propagate their written goal of advancing the cause of EVs. Adding a Service Center in the LA Basin? Far, far less potent - and therefore, inappropriate use of scarce resources (their capital, time and workforce).
Now back to time out. See y'all in late autumn.
