That begs the question why cars up until roughly the early 90's had an expected life time of 10-15y and have increased life expectancy now. Surely, it can't be hard to engineer parts of the engine or the chassis in a way that it breaks/corrodes after 10y. In fact, before zinc was used to protect the metal, that was one of the limiting factors. I think the answer is competition, and I don't see why there should be less competition for BEVs which are simpler to construct than ICE cars. Additionally, some managers claim that real-world battery life is much longer than expected, see https://www.forbes.com/sites/carltonreid/2022/08/01/electric-car-batteries-lasting-longer-than-predicted-delays-recycling-programs/ https://www.forbes.com/sites/carltonreid/2022/08/01/electric...
