The cars aren’t evolving the birds, but they are selecting the fittest.
Adrenaline is hell of a drug… and the best one.
I've seen the similar behavior from the ducks and geese in my neighborhood. Not as extreme, but sometimes I'm out for a walk, and they'll keep a wary eye on me, but will be content with the situation at 6-10 feet away, and won't actually take off unless I try to chase them. I don't think it's so much that they're "cutting it close" as that they're justifiably confident that humans are too slow to catch them at that distance and generally don't even try. But on the other hand, different groups of them seem to have different distances they're comfortable with. It's not like they've all solved the same optimization problem to three decimal places - some are confident and some are wary.
Of course, there are lots of stories of animals who got overly familiar with humans right up until the humans surprised them. As a funny example, I remember one time a cat that had grown up around my not-very-athletic family escaped the house and had to be brought back inside. At one point, it made a break for it along the long side of the house and was visibly shocked when my runner of a fiance ran it down and cut it off. This wasn't its first time running from us, but it had never run from him before, and it clearly didn't think humans could be that fast.
I don't think animals optimize as hard for benefit in everything as biology might lead you to believe. They build experience. They make mistakes. They're very cautious in new situations, but they can also be confident to the point of cocky if they think they know what you can't do. There's lots and lots of videos of cocky animals guessing wrong. It makes sense to me that maybe every individual animal isn't prudently optimizing hard for its own survival so much as that the group of them, with different temperaments, try different things and sometimes it works out and sometimes it doesn't and maybe there's a balance between weeding out dumb ideas and retaining the capacity to try things.
I think the idea that animals are always optimizing for survival and that everything must be for some benefit is misleading anyway. I mean, in an ultimate sense, you could say the same thing about humans, that they must always be optimizing for survival and reproduction, and whether or not that's true, it's definitely not true in a simple and obvious way on the level of day-to-day activities. We do a lot of dangerous and dumb and non-productive stuff. I don't think animals are different.
In fact, it makes sense to me to leave some reserve capacity. If surviving in good times takes all your time and energy, what are you going to do in hard times? Therefore animals typically have a lot of time for goofing off, and that certainly seems to me like what they're doing most of the time. They would similarly have room for trying stupid things and taking unnecessary risks.

I still remember the look on her face when I got to the corner before her. She looked at me like "what is this terrifying new creature?" as she stumbled backwards looking for a way to escape something faster than her. By the time she'd decided on a course of action, someone else (I think your brother) had grabbed her from behind.
I get that they have a lot of aggression and deterrence going for them. But in a fight between a goose and a human, the human is mostly risking bites and bruises while the goose is risking death.
I put them in a similar category of threat as scorpions. Of course I don't want to fight -- getting hurt is inconvenient. But if we do fight, I'm not really concerned about which of us is going to win.
Sure, humans should worry about crazy geese. Geese have a lot more reason to worry about crazy humans!
There's not a wasp on Earth I need to be afraid of, just friends I've met already and those not yet. I've hosted them in my kitchen, on my porch, been in the midst of a hundred drunk baldfaced yellowjackets and not only had nothing to fear but I knew it, not because they could not hurt me - I'm not so foolish as to imagine myself immune to their weapons! - but because I know how easy it is not to make them decide that they need to use those weapons on me.
I am very careful to walk small around geese and swans at all times, lest I inadvertently give cause to treat me as a threat. You'll do what you like, of course. No business of mine what you think of your chances. I hope the birds keep not taking you too seriously, and that you never frighten a gosling or God forbid a cygnet.
Where we stand on the respective odds of different humans versus different geese in different arenas, it's actually orthogonal to my original point -- that different groups of geese vary in their courage around humans, and that there are extreme outliers who are doing a lot more than "cutting it close" -- they're betting the humans will give them space. Or perhaps I saw something rare and was simply channelling Snow White that day. ;)
The more general point is that animal behavior need not always be thought of as the solution to an optimization problem. Whether you believe that's true or not in an ultimate sense, in an immediate sense, it is obvious that their personalities and experience come into play too, and that sometimes they make bad decisions.
Geese aren't confident because of some sort of rational assessment that they can put up a good fight against a human. Geese are confident because as a general rule, humans don't pick fights with them, and it's therefore safe enough for the group to hang around in places where humans are present at short distances.
Be kind. Don't be snarky. ... Edit out swipes.
Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.
When disagreeing, please reply to the argument instead of calling names. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."
I realize I made the point in a way neither disingenuous nor passive aggressive, and that this may be uncomfortable for those unaccustomed to directness in interpersonal criticism, or indeed that anyone should dare critique their behavior. Nevertheless.
I would address the remarkably mealy-mouthed, motte-and-bailey version of human chauvinism here on display, but what would be the point? Oh, one of you alone I'm quite confident of being able to pin down; neither of you argues very well in isolation. (No relation to Clarence, one assumes.) This back-and-forth, tag team crap, though, that's not worth the trouble. Go get yourselves an ass kicking from a tribe of pissed-off geese. As I said before, you're welcome.
For example: the allegation of not getting a word in edgewise, two against one, "tag team crap" -- I made one comment in this subthread about geese (my other comments were in another subthread about chasing down the cat), and it was in reply to my wife's comment in which she had stopped arguing that point. And then I responded to your unjustified insults by pointing out they are a violation of HN's rules. This is hardly an unbalanced conversation in which you have been unfairly targeted and not been given space to argue your position.
And of course declaring that "neither of you argues very well in isolation" is just a gratuitous insult. So is "remarkably mealy-mouthed". And, for that matter, suggesting I must have no relation to my rhetorically-gifted first cousin some number of times removed.
This is the sort of hostile trolling I expect on reddit, not on Hacker News. I kindly request you not reply to me again.
