Perhaps Leaf should learn from driver's behaviors and adapt itself to higher and higher battery SOC settings before it goes into turtle mode.. after all none of us want to see Leafs stranded on the side of the hwy, and Nissan would have to pay for the tow job after all.
Yes and no. There has to be a cut-off point where Nissan throws up their hands and says "We TRIED to tell you!!"
First, the "Low Battery Warning", both visible and audible. You get that somewhere around 17 miles. That's a LOT of time to safely get off the road and to a charging station or at least park it safely. Then, you get a VERY Low Battery warning, again, visible and audible. That's your last warning as your remaining miles show "---". The next warning you get will be Turtle Mode, reduced power, and that warning means you're about to shut completely off in very short order....perhaps as soon as 1 mile, but possibly more.
On an ICE, you get the 'low gas' warning light and then what? A dead engine.
Nissan gives 3 warnings before you go dead-in-the-water. I think that's plenty.
