I don't dispute that there is a market for Teslas, of the type you describe. But it's far, far smaller (for Tesla in its current incarnation) that you seem to think. It's absolutely a niche car manufacturer, taken together globally its a biggish niche, but it's definitely nowhere near mass market. Will Tesla ever break out of the niche? I've no idea - I see no sign of it yet, and to break out they need to appeal to a very different audience, those with little interest in an expensive luxury high performance car, but who want a well priced upmarket shopping trolley, as you put it, and with a reputation for reliability and service. VW, Nissan, Honda etc all understand that, and have a reputation in that market.
The car that did well in this mkt sector was the Nissan Leaf. It had very poor everything in terms of batteries & motors & for these reasons depreciated like crazy & is now being heavily out sold.
If your appraisal of the car market was correct then the Leaf ought to be still doing well. It is afterall basic, comes from a well known stable & is a nice shopping trolley.
As far as I can tell it is doing badly just because it is under built, the alternatives are better & the depreciation is murderous.
If any maker brings out a Leaf version of their motor they are going to do badly imho. The etron is a good example of a car destined to follow the Leaf into the scrap yard. It uses out of date electronics, is built from bits of other cars, under performs other electric cars & anyone buying one will be reminded that VW are a poor company, interested in misleading their buyers in any way possible to take cash off them as they did with diesel-gate.
