I'll just caution that new things are often over-built to some degree. Then "engineering" is often how much margin they can squeeze-out while still hitting their warrantee targets.

General Motors built an ignition switch for decades which worked mostly just fine. Then they built one so crappy that they killed a bunch of people. Only to save 25 cents or whatever.

EVs depend heavily on 'early adopter evangelism'. I wouldn't read too much into this.
