It is disappointing that Tesla uses much of its engineering prowess to design products that are inherently difficult for owners or small shops to modify, maintain, or repair. Taken directly from Apple's playbook.
Tesla is probably doing the same.
Remember a good number of repairs Tesla will end up paying for - through various warranty schemes - so they care about repairability too, just to a lesser extent than they care about product performance and cost.
Thought experiment: Imagine that the overall material required is cut by 10-20% by tons of optimizations and reductions. That means the supply chain and associated energy/costs vanish. If you have a failure rate of less than that (probably much less) scrapping is likely still better.
Also dropping a broken car and building a new car takes manufacturing costs.
Teslas (especially the Model 3 and Y) are not inherently difficult to repair. The problem is that Tesla's restrictive policies make it difficult for individuals to access the documentation and parts to do so.
I'm not even sure there's a tradeoff here, since bending a frame of any car is bad news whether or not its one piece.
He's actively against public transport (which is by far most ecological), pursuing dreams of living on Mars (which is unpractical on so many levels, that if it'll be ever complete, it'll be trip of lifetime to fifthly rich people), building expensive toy cars (car that does 0-60 in less than 6s? who would even want that?) and many more.
Boring company, aka, private tunnels for Model 3/S/X (https://electrek.co/2020/07/20/elon-musk-boring-company-tesl...)? It's as much of a public transportation as Uber.
Hyperloop, aka vaporware?
