@neil - I have a 2021 Kia Niro which I'm generally happy with, although I've probably done less due diligence on the privacy than I should have done. I can get comfortably get from Cambridge to London and back on a single charge, or Cambridge to Oxford if I charge while I'm there, and I'm very conservative about how close to 0% I'll let it go. For normal driving we change it about once a week, but we could get away with much less.

Kia have recently made the associated app much shittier, but there's no real need for me to use it. Annoyingly, at the same time the Ohme (charger) platform stopped being able to connect to the Kia platform which means my charger can no longer automatically schedule charging to get the battery up to a specific level - I have to manually tell it the starting value each time.
