Thanks for the math to back up my own doubt. Fortunately, the bus analogy appears to be added by the author as a bit of sparkle and does not get brought up again.
You don't have the same results from bus:human::raindrop:mosquito, but the size comparison is a useful measure. I didn't realize a raindrop was 50x the mass of a mosquito. I thought they were roughly the same size.
Further, it reinforces or introduces the idea (along with the conclusion of the study) that "So small things are inherently stronger with respect to their mass."
Lastly, this is National Geographic. Anecdotes and analogies are useful to communicate to the general public.
