Have to wonder if Toyota still have the keys to the NUMMI plant.
All of those companies - and the entire industry - are investing heavily in their own electric cars; some already have announced dates when they will stop production of gas engines IIRC. Depending on the price, of course, I imagine they'd love to add Tesla's prestige, patents, and maybe their talent.
My uneducated guess is that's how Tesla will end, a division of a major car-maker. When did GM last add a new brand? Imagine the bidding.
Toyota might be better at building profitable cars, but Tesla is better at building profitable EVs.
Have you actually looked at the production numbers of those other EVs? Because there is nobody outside of Tesla that has mass produced EV and even more imprtantly, to do it with profit mergin per car.
Teslas are the Top 3 most sold EVs in the US market. The model 3 is by now equaling the sum of all other EVs and is almost 100% of the growth in EVs.
Futhermore, the iPace, i3, Tycan and many others saw production delays as well. So the idea that you can let some established company do it and they will do way better then Tesla has jet to be shown.to be true.
The original Tesla Killer, the Bolt, is outsold by Tesla 15 to 1.
Competitors have announced many EVs but most will hit the market around 2020 and most of them will not produce near as many as the Model 3.
What's clear is that we know Tesla has had (and may continue to have) issues with production. Meanwhile I can't find anything suggesting there were any production issues with the Chevy Bolt or Volt or Nissan Leaf, the other models I'm familiar with. I'm not familiar with any of "iPace, i3, Tycan" so I don't know what to look up there to see if there were comparable issues with them.
Guess why you don't know about them, because they don't sell well or are delayed.
Tesla will always have production issue because they are always trying to grow. Every large company has production issues. The question is how much product can you produce at what price.
