I think it stems from people being really poorly equipped to think about scale like that. Even someone who has lived in NYC and/or been to jam packed sports stadiums, you're still only around ~50k humans max and that comes out to around 0.005% of drive users. So if a developer comes up and says a change will only effect 0.1% of users it may seem like a insignificant percentage but the actual impact is something to the effect of 20 full stadiums of people, massive.
