Nissan created a PowerWall-like division for the secondary market. That division made a commitment to only ever use secondary use batteries. (Unlike PowerWall which has yet to build one from secondary use batteries. They use fresh manufactured batteries.)

Nissan's early Leafs have the reputation as the cars with the most degraded batteries coming back into the used car market, and some of Nissan's earliest Leafs were sold under a "battery leasing model" where the car was sold but the battery was still under lease from Nissan giving Nissan incentive to replace the battery if it dropped below certain warranty thresholds. Yet despite the "notorious degraded Leaf battery" and decades of the Leafs existence and batteries that possibly owners could call in lease terms for replacements out there, statistics show that the vast majority of Leaf batteries are still in primary usage (people are still driving those "degraded" batteries, there is a used car market for them) and Nissan claims they've yet to see enough batteries enter the secondary use market to build even a single one of their PowerWall-equivalent products.

I wonder how many households realized they didn't need all that range after all since they have a second ICE car anyways. So the Leaf pretty much stays in a 30 miles radius of the house.

From my own anecdotal evidence I think a lot of people absolutely underestimate the impact of home charging (even at "trickle" Level 1 in the US) versus "range anxiety". In the nearly a decade I've had my PHEV, two of my three daily commutes I could and did entirely every day on the range I can Level 1 trickle charge entirely at home overnight.

People massively over-estimate the range they think they need because they don't take things like home charging into account.

Exactly this.

From a regular European 230V outlet you can get 100km of range every night easily. Even more if you don't work 16 hour days.

The average commute around here is a bit over 50km a day, both ways combined.
