I do care about mine. The point is the difference between ideal and within design normals is huge. However the outcomes are very much less so, to the point of the differences get lost in the noise.
If Person-A babies their car and goes out of their way to keep it as ideally as possible and Person-B not only "just drives it" but abuses it, purposefully doing things that are opposite of known ideals, you can then start drawing conclusions about how much babying versus not babying makes a difference.
In real world scenarios, the human behind the wheel doesn't have a huge effect over the life of the vehicle. Things like climate and age make the most difference. The battery is happiest when humans are happiest as a general rule of thumb. If you're hot, the batteries are hot. If you're cold the batteries are cold. There is an ideal temperature and when we test batteries in the lab for other conditions it is done in temperature and humidity controlled chambers to reduce that variable as much as possible. Then there is a much bigger range outside of happiest where we can call it just happy. That is basically the entire range that isn't red on the Leaf. It is not ideal, but it is perfectly acceptable for a lithium battery and the damage that excess heat does over a lifetime may be measurable if sustained for a very long time but generally not.
The short of it is if you baby the car you will get X miles out of it. If you abuse the car you will get Y miles out of it. X and Y have almost no correlation because of all these other factors. If we were neighbours that were identical twins and drove the same routes at the same time to the same places in the same climates etc etc etc, my abused car will show more degredation. But how much? Doubt it can be measured. I have more range and capacity than most others at similar age and miles that have taken the baby approach to the pack because I live in a climate that makes the car happier.
