I haven't ignored that data point. But I'm also aware that there is much more relevant and important data to be considered.
For instance, the largest car market in the US is the under $30k price point. Tesla has zero car sales in that market. It would appear that you are cherry picking one fact and ignoring many facts to get to your position. To really get mass market adoption, we got to get to that price range.
In 2018, that under $30k price point will be about 3 million units in the US alone, probably more as I stopped adding the YTD column after the top 15 models - all available under $30k.
And I concur on what Americans 'want'. But that isn't what the masses are buying. They can't afford it so they settle on the under $30k market as an adequate product. Ignoring that reality is not a good way to create realistic strategies in support of EV adoption.
I'm not saying Tesla is bad or shouldn't exist as an option. It has its niche. And the Model 3 is expanding that niche to a lower price point than their prior models - and that is getting well received by that new market niche as the data clearly shows. And the SR version will further expand that to yet another market segment. Hopefully they will do another model that brings their wonderful products into an even lower price point. But even if Tesla had 100% of the current EV and PHEV marketshare, they would still be a niche product. Having the lions' share of a small niche doesn't translate into widespread adoption. Having an adequate product under $30k is where that potential will have to play out. The masses simply can't afford over $30k cars. Therefore, the masses won't be switching to EV if that is the only product because, gee, that is what the well-heeled early adopters liked and therefore is what the market will demand.
On the plus side, Tesla sales are expanding nicely and as they resolve their capacity issues, should continue to do so. So, yes, they likely will continue to have the lions' share of the current and imminent EV market. But having options that include smaller batteries and PHEV that pitch to that under $30k market will get some on board who can't or won't pay that much of a premium. And each of those units will help in the conversion from gas and help cut emissions now, rather than [what's the latest estimate for Tesla delivering a product under $30k?]
