Ars debunked this weird idea that batteries aren't improving a few years back: https://arstechnica.com/science/2021/05/eternally-five-years...
And even if we did get a 50% battery capacity upgrade in 2025 as compared to 2024 - while I wouldve lost the bet... My original point would've still been just as correct, because even at that point, they're still annoying to work around vs ICEs and their biggest cost would still come from a single component (battery) that has a pretty short expected lifespan compared to a regular engine
And you yourself likely know that as well, considering you didn't even acknowledge my bet ( ◠ ‿ ・ )
I'd also argue we're seeing battery improvements in cars pretty consistently, which is one of the reasons I can now buy an EV with 350km range for AUD$30k.
There have definitely been improvements in that regard, just not in such a short period of time
