With my 2011 Leaf, I know I can travel 10 miles on the last bar, 20 miles on the last two bars, 29 on the last three bars and 37 on the last four bars. This is with fully inflated tires, the climate control off, keeping the speed below 50mph, never accelerating hard enough to have more than 3 power dots filled at once (there is always one filled), and only using regen or coasting to slow down. If I keep the speed under 35mph I can get another mile or so per bar. I know to never be more than about 35 miles from home when I get to the last four bars. Since the miles per bar on the first 8 bars is significantly less it is essentially impossible to be more than 35 miles from home before getting to the last four bars. The last four bars is about 50%. However, it is possible to be more than 20 miles from home with only two bars left. I make sure I plan to avoid this situation. Of course this algorithm gets thrown off a bit because a bar gets erased every time the car is power cycled. If I'm on a trip where I care, I have to make sure I notice how many bars are active before I shut it off.
