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.
It's a completely useless measure though because the laws of are the same regardless of size (although some things scale with the size of the *planet* you're on) Like it takes the same amount of energy to accelerate per gram regardless of you're accelerating 1 gram or 1 ton.
So if two things have the same *energy density* (i.e the amount of energy per cell is the same regardless of the number of cells in an animal) then they should be able to accelerate around the same rate/take about the same energy to move through the air.
Angular velocity is a better way to think of it; also explains why that jet looks like it's hardly moving from the ground going 3x that speed at altitude. That mite would look a lot slower if the camera lens were further away.
