We wanted a scenario where, say, 5 well-placed border points could efficiently represent an area with 5,000 internal points and 10,000 road edges. This would reduce those 10,000 edges to just 5*4/2 = 10 shortcuts for routing through that cluster at a high level – an incredible 1:1000 point ratio and a 30x reduction in edges to consider for the high-level path!

I’m not an especially fearful flier, but I dread turbulence all the same. I avoid seats in the back of a plane, check radar maps before a flight, and keep my seat belt buckled even when the light is off. I remember a conversation I once had with the forensic anthropologist Clyde Snow, who spent years investigating plane crashes for the F.A.A. In his experience, he said, when a crash did have survivors, a disproportionate number of them were men: they were the first to shove and claw their way to the exits. As he put it in 1970, in a study that included two plane crashes in which the passengers had to flee from burning cabins, “It appears that younger males were definitely favored . . . where speed, strength, and agility would be expected to play a dominant role.” In those two crashes, even the old men survived at a higher rate than the adult women and children.
