Didn’t know this was a thing. I arrived at the idea independently after noticing big airliners on landing approach look like they’re moving very slowly, but are actually moving at 150+ mph. The body-length speed explains it. We’re biomprphically wired to process speeds that way.https://twitter.com/rainmaker1973/status/1351950104824078342 …
Animals we encounter ordinarily, not counting whales, are generally at most 3x-5x humans in max dimensions (elephants, giraffes) so our body-length speed sense does not feel that far off from objective speed. But huge vehicles throw us off. Oil supertankers are the most extreme.
Even with animals, this can throw us off. Elephants seem slow and lumbering but their typical top speed of 25mph is close to human *record* of ~28mph. An average human will not outrun an average elephant. We forget their legs alone are taller than most of us.
Rolling cannonballs, the ones that had fallen to earth and kept going, seemed slow enough to stop with a foot or God help you hand in the 18th century. They weren't, and given mass would take the limb clean off.
