Unlike in the animal kingdom, safety would come from being noticed, not from avoiding notice. I'd think people would be unlikely to
not see you, and so they might be less likely to hit you while they're munching their Mega Pork and Bacon Burrito or texting their friends about the fat guy they just saw dripping a Mega Pork And Bacon Burrito all over himself.
Plus, they're bound to be at least as safe as one of
these tiny things.
