To be fair, having 14% left would induce extreme range anxiety in lots of people - like my housemate, who drives a PHEV even though she never drives more than maybe 60 miles. The one time she used my 2013 Leaf to drive to work and home, she shut the heat off immediately after leaving here, got home with ~35% charge left, and considered it an unpleasant experience. Not because of no heat, but because she got so close to empty...
I guess everyone's different and those who have more experience near the bottom and know their car have no issues. On my '13 Leaf, I leave to work with no lower than 25% SoC. It's about 12 miles to work (slightly more or less depending on the route). I know it takes maybe 12 to 18% to get there on a dry day so 25% is more than enough. So, I pass LBW, which is no problem. Even if I hit VLBW, no problem, I'm almost there and I have free charging there. The only possible detours involve cutting my highway driving to 0 from about half of the driving by time.
On rainy or wet cold days, I leave w/no less than 30%, just in case.
