I once read an opinion that stated that Tesla will eventually lose because they don't continually introduce new or updated models (say, every year) like other car brands do, and that person thought that they will lose customer favor because of it because their cars will be "the old thing" with no "new thing" available. In other words: Cars are fashion too, and Tesla only has one entry in each category. It's a good entry, but it's only one entry nevertheless.
I thought that was an interesting observation, and I've been reminded of it ever since. Maybe that person was right.
While unlikely to be that person, haha, I have mentioned that before. And I think the fashion argument is just one part of it. This whole time, it has showcased a hole in Tesla's capability. They simply aren't able to iterate their fleet. Look at Kia and Hyundai. They have dozens of models across all sorts of markets, and they were able to waltz into the EV market with immediate success. They already have more EV and hybrid models than Tesla's EV models and are quickly adding more. There's also an argument that hybrids are a growing, relatively untapped market sector, something Tesla is unlikely to be able to expand into.
An interesting take. I think we're already moving in a direction (at least in the US) where Tesla is becoming less "cool," but that's mostly because of their CEO, not their cars.
Tesla targets a very narrow range of the car market. It doesn't make much sense for them to have two similar-sized models, because the Venn diagram of "people who want an EV" and "people who want a $SIZE $BODY_STYLE" is already pretty narrow.
Did you not know that the Model S and X had new body, interior, mechanicals just a couple years ago? Making it the quickest production car ever made. How is that ancient history?
That's just a single example. To add just such an example to the other end of the scales: their factories still move at a glacial pace. Even a tortoise is faster.
