🤷 I agree. There's no evidence for any of this yet, but at least this Tesla (yes, gross) has made it past a million miles: https://www.motortrend.com/news/heres-a-million-mile-tesla-model-s-owners-advice-for-ev-reliability/
Albeit with several motor & pack replacements. So I dunno. I'm in the "let's try something different for new, but recycle what already exists" camp. My 40yr+ motorcycle is already made, and while not the fastest or particularly efficient, is still fun to ride and repair. An EV by nature of having far fewer parts should be more reliable once we find out what parts to strengthen, and more vehicle design strategies are evaluated.
That is nice, but an ICE vehicle like your bike can go that far also IF you replace all the parts as they wear out. Diesel engines can go that far with proper maintenance and repair and at a lesser cost. The problem is, EV parts and replacements are prohibitively expensive. Which still makes them too expensive for us plebes to really own.
Such is the cost of progress. Considering how much of an established supply chain ICE cars have, it's amazing that a zero CO2 output EV has higher efficiency, and reliability. Think about it: after more than 120 years of optimization, 40% thermal efficiency is the best we've got. Considering how energy dense gasoline is, that's a crazy waste, global warming concerns aside.
The weakest point in the whole strategy is the battery pack, which it's likely we'll soon discover some alternative to with this much market pressure and scientific interest being focused on it.
For the record: you can ship of Theseus anything. But do people? Not unless it's a critical problem, so you have a degraded vehicle with higher emissions than designed for at the factory. Secondly, who wants to invest that much downtime over and over? I don't mean to sound rude, but that whole first part is an admission of Stockholm syndrome 😋
The point still stands - unless EVs become cheap enough for the average buyer, they will be a nearly useless novelty item for the wealthy. And they will never be enough of them to solve any issue with emissions you don't like.
And that "better" and "cheaper" battery is still most likely decades away - despite all the pop media articles talking about all those incredible laboratory "breakthroughs" that are supposedly ready to be unleashed. The gulf between the lab and the production line is very large.
And you are correct that few people are willing to keep repairing anything forever unless forced to. And that is precisely why an inexpensive entry level EV is so important. And those high end cars far less so........
That's the point I'm agreeing with. The wrong market is being focused. I think the horse has been beaten into glue at this point.
As for the rest, it's gotta be done. If it were a simple problem, it'd have been solved by now. Worrying about quick returns on investment are what destroyed the world around us as we know it. I work in R&D, progress is incremental... Until it isn't.
