All this battery talk could be described as Quasi-engineering puffery! None of it matters if it doesn't result in satisfying customers' needs.
In terms of engineering, nothing has changed since Brunel.
Engineering is doing for 6p what any fool can do for a schilling.That is why the tech that goes into electric is important, it is why all the offering from legacy auto are lame.
Most people have no clue what so ever about science and engineering.
What they can understand is performance and those who test drive a Tesla and then most of the competing offering from legacy get the engineering difference at a primitive emotional level.
Sure the reviews go on about how good some legacy offering is, but they are all being paid to say this. It is very much more difficult to argue with the emotions of the folk behind the wheel and all of that comes from the build and the ingredients.
I understand that all of this will make no sense to you, as like most people you are a product of the marketing industry and have what it has wanted to put in your brain all ready to go and argue and to add to the mix you have had good experience with legacy.
What I believe you don't know or understand is the future and how things have changed.
Of course I might be wrong, if I am the Tesla stuff won't sell and the business will collapse.
