Ingrained attitudes.
Imagine your idea of a dream car is something like an Audi RS6 and that you lust after the four exhaust pipes and the noise they make.
Imagine that you have bought a few cars and worked somewhere in the auto trade for one of the big three. You would then sneer at this production volume and consider Tesla to be amateurs, nothing but a side show.
Imagine that you dropped out of doing something for society and have been rent-seeking for many years and no longer think of the collective good but just for yourself. You really would not care about the bigger ideas of moving to a carbon neutral world.
Imagine that you are baby boomer generation and simply do not think electrification of vehicles is a practical reality in your lifetime or your great grandchild's lifetime. For you the world is made of compromises and you were quite happy to gas children with lead in petrol for most of your life without questioning it.
Imagine that you gamble on the stock market or ponzi-coins and only think of opportunities to make money that way rather than creating something of value by actually investing in companies you believe in.
Imagine that you have a narcissistic personality and cannot for the life of you express an opinion that is positive about something you like. With such emotional limitations you could only criticise and point out failings.
Imagine that you work in the media and have the Western Media Mindset that is best described as passive aggressive. If you had to write stories then by definition, because you only work in the media and have never made a car or a component for a car in your life then you could only make stories about failures. Bad news sells papers, idle speculation gives likes and views that can be monetised.
There are lots of people in the world that have these traits and because Tesla are doing something a bit special it attracts them. They write nasty things and say nasty things. They also do not have anything better to do.
This is not to say that everything in Tesla world is perfect but the people with valid criticisms get drowned out by the empty vessels who are not quite empty as they are full of greed and other emotions best left in the playground.
We also live in a bubble and there are only so many places one can put one's money. Many things including everyone's houses are somewhat over-valued right now. Tesla's valuation is not over exceptional. The naysayers also lack the time to study their history and many successful manufacturers started out with massive backlogs and production difficulties. Citroen is one name that comes to mind.
I see Tesla problems as more akin to software engineering. It is easy to criticise a software product and see the many fixes that could be implemented easily but that is not how it works. This we all know on HN but pundits on the news don't.
