The human brain is horrible at building truly accurate 3D representations of the world. Our mental maps are constantly missing a magnitude of details while tricking us and creating approximations to fill in the blanks.

Easy examples of this are optical illusions, ghosts, and ufos. There is also "selective attention tests" where a majority of people miss glaringly obvious events right in front of them, when they're focusing on something else. Regular people also tend to bump into things, spill things, and trip, even when going 3 miles an hour (walking speed).

Exactly. We don't build detailed accurate 3D maps. We build fuzzy semantic 2.5-ish-D maps that are 99% metadata. And they work incredibly well.
But at the same time people don't think much about getting in their cars and driving to work or the grocery store.

So it seems that a truly accurate 3D representations of the world are not necessary, at least for driving. Perhaps it's the resolution? Looking at the samples in the article, they are just terribly fuzzy, with a narrow field of view. If I had to drive and only see the world through that kind of view, I don't think I would be doing very well.

People also crash all the time. I'd be OK with AI crashing even slightly less than humans. Rabid shock-media and various luddites aren't.
