The other day I got a little nervous the first time I went below 70miles of range. But my fried with a leaf can't get that far on a full charge. And also I drove the first week of ownership without charging at all, so no real need to worry...
I was worried about it being a thing but it hardly materialized as a direct thing and within a week or so it's not really what I'd call anxiety. In 5 months I've been below 20% exactly once, I got down to about 15% (roughly 40 miles) when I got home. It took a bit to internalize the planning and I expect I'll push it a bit more with time, to see where the limits are. It's just that it hasn't really come up. A >200 mi range really is a lot.
I think it is still sort of there, with indirect impact. My wife won't leave home with less than "full" charge (use Hilltop mode, 90% is "full", to minimize battery degredation ). I do but really almost always it was planned ahead. Because you have to drive hours to bring down the battery you've got a lot of empty time to use to plan ahead. So I already have a pretty good idea where I'm at.
There was once where I had to consider really pushing the range, it would have been tight (maybe sub-10%, potential I wouldn't make it). But then the situation changed and there was'n any call for it.
With 300+ mi range I can't see how it would EVER come up around home. I expect the only time will be trying to make it across a large, unnatural gap in the SC network (which at this point still exist), or I've brain-farted and forgot to plug-in when I last got home. Even the later I'd probably have to do that twice in a row, and also be headed in a direction that doesn't have a SC or be very pressed for time.
I was at 61,000 when I sold it in 2016 for a new 30-kWh LEAF. Losing 3 bars put me too close to the edge for my daily commute and the Model 3 was still years away, so the 2016 LEAF bridged the gap for me. My 2016 LEAF now has 35k miles and has lost no bars so far (LEAFSpy indicates 89% battery health so I'm close to losing the first bar). I'm still getting used to the idea that I can go anywhere I want in my 3!
