For their design goals at the time, I think it met them just fine.
Now that they have figured out that being able to build TNGA and E-TNGA on the same assembly line isn’t probably going to make their cars as cost-effective to build as a dedicated platform with additional engineering, they are definitely rethinking things.
While being a ”work of art”, and of integrated design, I am personally not impressed with Tesla’s ability to build their cars in a reliable way. Telsa has a totally different corporate goal than Toyota, and the build quality and consistency of their cars shows the differences.
A decade ago, I told people that when Toyota built a BEV for me, I’d buy one. And I did, while it happens to have a Subaru badge on it. Enjoying my Solterra.
