According to a report by The Washington Post, Elon Musk overruled a significant number of Tesla engineers who warned him that switching to a visual-only system would be problematic and possibly unsafe due to its high risk². Despite their warnings, Musk was unconvinced and overruled his engineers. In May 2021, Tesla announced it was eliminating radar on new cars and soon after began disabling radar in cars already on the road³. This resulted in an uptick in crashes, near misses, and other embarrassing mistakes by Tesla vehicles suddenly deprived of a critical sensor².

In 1909, the biologist Jakob von Uexküll noted that every animal exists in its own unique perceptual world — a smorgasbord of sights, smells, sounds and textures that it can sense but that other species might not. These stimuli defined what von Uexküll called the Umwelt — an animal’s bespoke sliver of reality. A tick’s Umwelt is limited to the touch of hair, the odor that emanates from skin and the heat of warm blood. A human’s Umwelt is far wider but doesn’t include the electric fields that sharks and platypuses are privy to, the infrared radiation that rattlesnakes and vampire bats track or the ultraviolet light that most sighted animals can see.

The Umwelt concept is one of the most profound and beautiful in biology. It tells us that the all-encompassing nature of our subjective experience is an illusion, and that we sense just a small fraction of what there is to sense. It hints at flickers of the magnificent in the mundane, and the extraordinary in the ordinary. And it is almost antidramatic: It reveals that frogs, snakes, ticks and other animals can be doing extraordinary things even when they seem to be doing nothing at all.
