This is exactly why I’m so uninterested in driving en EV. I usually word it as “I don’t want to drive a computer”, but the reality is that I don’t want to be on the wrong end of the power imbalance that comes from this amount of complexity.

Is this an issue with all BMW PHEVs or just one model from one year?

There are tons of used BMWs on the used market here in the states. They don't hold their value because everyone knows that some stupid thing is wrong with them that either can't be fixed or is so ludicrously costly to fix that it would be more than the whole entire car is worth. BMW is a shit company, doesn't matter if it is ICE or EV or whatever it is, they're intentionally made to be impossible to repair cheaply. It would be so easy to build "open" hardware and have onboard diagnostics built into the cars, but no.

This makes me feel that peak car was 2010 ish, when, when engines were powerful, cheap, and not too polluting, but also not overly complex.

Spare parts were small, cheap, and easily accessible too (atleast for my toyota)

I dread being forced to upgrade, not out of disdain for the environment, but the fact that I will spend more money, on a less reliable, less "mine" car, and more something big daddy government wants.

I think it continues to be under-appreciated how much of a lead Tesla still has in EVs. Even BMW can't make something that is practical.

First people said "competition is coming" for about a decade. Now the competition has finally half arrived, but it's still so far behind. Perhaps the closest is BYD, but most BYD drivers would prefer to be driving a Tesla.
