I don't think is fair. We actually don't have a lot of data on real world battery lifetimes, but a properly engineered system with good heat & charge mgmt can last a decade for sure. There are 2011, 2012 Chevy Volts on the road like this, with minimal degradation, from my understanding. It is true that some manufacturers (cough cough Nissan) have been slack on the battery longevity front. But Tesla and GM at least put a lot of engineering into temperature and lifecycle mgmt and I expect others are now doing the same That and I'm sure in the long run, cost effective battery replacement will become entirely feasible in various manufacturer pipelines, once things mature and standardize. Meanwhile in an EV most other components will have a longer lifetime.
