Just listened- great hangout- and many thanks to CapOp for doing this and sharing some excellent thoughts and expertise. I especially can relate to the concerns regarding scaling making similar arguments to those that too closely equate Tesla to Apple/Google/Msoft etc.
The ability to scale per $ invested is simply not in the same league. Without diminishing that point one bit though, the comparison to ICE manufacturers is what Tesla competes with. Elon-team have applied scaling per $ invested (due to extreme vertical integration and EV only design) to an industry that hasn't seen this ever (but similar in disruption to the ModelT). The Tesla model for scaling per $ invested is an order of magnitude beyond what a current ICE manufacturer can accomplish IMO (while still not approaching consumer electronic/software of course).
In short, I see 2105 as a seminal inflection year for Tesla. The confluence of 3 world markets, 2 successful models under unmatched vertical production, SC network largely completed or partial (China), Giga-Factory reveal and detailed, direct sales and support network largely implemented, and a reveal of the ModE. By the end of 2015 with all of that largely in place, I believe the question of valuation inflects relative to the market. The current valuation of $30B- compared to half of BMW $60B which induces your scaling pain, will inflect from 'does Tesla deserve to be half of BMW given scaling issues?' to 'with Tesla now in the marketplace, does BMW deserve a $60B valuation?'
At that time, assuming Tesla has those above items accomplished, they will have demonstrated unprecedented scale/$ (relative to ICE), the investor community may well be reversing the question, how does a BMW prove worthy of forward growth. Until they can demonstrate the ability (or at least the path) to a higher performance/safer/low maintenance product, without an ICE engine, direct sales to customers, free 'gas' for customer long distance for life, battery scale capacity, an overhead plan that shows ICE engineer layoffs and replace with electrical, etc. etc. Once that inflection is reached, the Tesla valuation is likely justified to be twice BMW rather than the other way around, just based on the clear path of the industry as displayed by Tesla and the questions about who has the ability to follow that path.
Might be one of those BMW ICE factories becomes the next Tesla-Euro 'for-a-song' purchases...
anyway - great discussion on the hangout; your insights and research continue to be hugely valuable and appreciated
as usual many thanks DaveT and others-
