TIL that the Convair Model 118, a tentative flying car from 1947, was shelved because its prototype crashed when a test pilot mixed up the flight engine's fuel gauge with the road engine's and didn't see the former run out. While he survived, this killed interest in the project.

TIL that the geologist Michel Siffre spent 2 months underground without time cues to study how his body clock adapted, repeated the experiment for even longer on himself and more subjects, and discovered that their bodies tended to switch to a 48-hour clock. In one case, one even slept 34 hours.

I guess it was assumed that if a pilot could make such a trivial mistake, inexperienced drivers would definitely make it too.
