The LEAF's "GOM" (Guess-O-Meter) is pretty pessimistic, and there usually is more range available than indicated once you get to that stage. You get 2 verbal warnings; First is "Low battery", Followed by "Very Low battery", then comes the "turtle" mode in which the verbal warning is "Power Limited' and it begins dialing back throttle response.
The guy in the video was supposedly worried about making it home, yet he's going 68mph UP-HILL on the highway! All he had to do is slow it down a bit and he'd have lots more buffer.
He seems to even admit he's diving poorly when he comments about his chopped-down tree on the Eco indicator!
I could have made it home without even bothering to charge simply by driving carefully. I've done 120 miles, including a good chunk of highway, when I've needed to.
Still, he's driving that far to work and he doesn't even have Level 2 charging at home! Unbelievable!
Rather than relying on the horrible GOM, here's a better idea of the range capabilities of the LEAF, courtesy of Tony Williams:
