> The existing car companies are all off doing their own thing e.g. VW ID.3 (hatchback), Hyundai Kona (mini-SUV), Renault Zoe / Chevy Bolt / Nissan Leaf / BMW i3 (small-car) etc.
I'm not sure those are the strongest examples, as you can defend most of them (maybe not the BMW i3) as perfectly legitimate cars in the current market and maybe more than Tesla's counterparts:
* The S and 3 are almost retro in how much they resemble a traditional sedan, and supposedly that's not what Americans want in the current marketplace. (Enough so that both Ford and GM saw boosts on the stock market for abandoning the entire class of vehicles [admittedly, to imports and the S and 3].)
* The X looks like "soccer mom" minivan more than SUV, and I've seen Americans look down their nose at it as "uncool", very cool falcon doors aside.
Meanwhile:
* VW ID.3 looks like a modern reinvention of the classic VW Golf, a tried and true decades-spanning form factor. The VW Golf itself being something of the grand-papa of the modern hatchback trend and influencing almost everything else on the market (the Prius, the Tesla Model Y, everyone owes at least a little something to the Golf).
* The Hyundai Kona is in a class of SUV that is very popular in American and abroad. (Look at uglier ICE relatives like the Nissan Cube and the Honda Element, both of which have been relatively high sellers, despite their boxy, not-quite-a-full-SUV thing.)
* The Renault Zoe is in a somewhat common form factor space for European cars. Compare the Mini and the SMART.
* Chevy's Bolt is trying to be a normal "cross-over", and that's again where GM and Ford are almost entirely focused outside of trucks.
* Early versions of the Nissan Leaf were hatchbacks of a Prius (or Tesla Model Y) sort, and recent versions look like tradition sedans.
All of that is of course my opinion, but claiming that the existing car companies are doing their own thing and Tesla is somehow the only one doing "proper" cars seems to be the inverse of reality: Tesla is doing their own thing, and everybody else is trying to do what they think the market will best support (and it is not traditional looking sedans).
(Plus, the VW ID family is already gearing up to eat the rest of VW's lineup as they drop the diesel lineup like its hot. BMW is doing the same. We're about to the tipping point where EVs are beyond early adopter-focused, one-off models, and manufacturers are about to hit every form factor with an EV or two.)
