also check out the "gnomonic icosahedral" at H0 from the dropdowns, that's the projection the base hexagonal grid is from, it's a perfectly planar hexgrid on an unfolded icosahedron net.
There’s gifs of hexagons on a planet you can search but you can’t cover a sphere with just hexagons. Even so, I imagine the poles are irrelevant to Uber
The image shows a number of pentagons, so it's not just hexagons unless you consider a pentagon some kind of degenerate hexagon. That said, you can indeed cover a sphere with only hexagons, if you relax the requirement that they all be regular hexagons.
If you have only hexagons, you end up with 6 vertices on the sphere where only 2 hexagons meet (whether you still consider these to be "hexagons" when they have two adjacent sides is a matter of definitions).
But what many spacial indices do instead is include 12 pentagons among the hexagons.
