People will never understand Tesla unless they understand it really is just a car company.
There is no magic leap here. Cars are becoming smarter, and more electric and car manufacturers have been adjusting all along.
Most car buyers are not caught up in the heady-dreamspace that the Tesla brand is built on - they will just by what they perceive to be value at price.
What is 'amazing' is that someone was able to actually break into making cars in the 21st century! That's a hell of an achievement.
But it's just a car.
Although there may be a Magic Leap here:
Some of this is from the simple fact they are first and their offerings are very unlike traditional manufacturers. Most competing offerings are forever denoted with the asterisk of coming in 2022 or later. There should be more offerings this year to include Ford's Mach E but the real test here isn't that the public wants it, the real test is will Ford increase supply if demand is there. I don't feel like Chevrolet/GM has done that. VW is the real contender if they hold to their statements of how many cars they intend to push
Still Tesla needs to get their act together. Customer service is a sore spot and getting in contact with levels higher than local service centers is far too difficult. They also have reduced content in the 3 and Y instead of increasing it; no default homelink and remove auto dimming mirrors. They seem to was to pass off games and features while parked as more content instead of what improves QOL of living with a vehicle.
Long term we need Tesla so that manufacturers don't try to force us into settling for ranges of 250miles/400km which a lot of future offerings are. Just like they would not make EVs over 100/160 until Tesla forced their hand they won't be pushing 300/500 unless pushed.
Tesla only has to solve scale (which they're beginning to do) and spare parts availability (which is going to solve itself but it needs time to build out a network) to utterly dominate the car market of the future.
Not to mention most of their RnD and their capex goes towards manufacturing cars.
