I agree the lack of liquid cooling on Leaves is problematic - I see their batteries die much sooner, often under 10 years. But it’s fine if you don’t live in a hot climate.

They also replaced the batteries on every 2017-2020 Bolt between roughly 2022-24 with warranties until 2032. So by buying a used one now, you get a car with a battery that’s only 2-4 years old, not 6-9 years old. That alone makes them worth it.

The first two generations of the Nissan Leaf and the Chevy Bolt are the closest to what you’re describing.

You need a lot of money for incentives. The bigger factor is large scale adoption among the corporate apps that others use (their privacy policies notwithstanding), which I realistically see never happening for Graphene, sadly. Sideloading is a decent alternative, I just don’t know how long it’ll be around for.
