Used to love playing with the coyotes in the Rural northeast as a bored teenager. MY brother and I would crouch in the long grass in a 300 acre hilly field and see how close we could get to the coyotes. I don’t think We were sneaking up on them, they just didn’t see us as a threat. Once there were 4 rather than the usual one or two and they started circling us which was both amazing and nerve-wracking. Eventually we stood up and waved our arms and they loped off at a very unconcerned pace.
Some of them just do not see humans as a threat. This one in unincorporated Cupertino walked at me for a quarter of a mile and then walked past me.

There's one in La Honda for at least a few years that does not move when I go past on the road, it just sits in the road and makes people move around it.
In Chicago I had a particularly fat one saunter right past me, a few feet away, before dashing across a busy four lane street into a cemetery. He was clearly not fazed by me, or traffic, at all.
(It was across Western, for anyone wondering)
There was also this famous incident of a coyote who casually walked into a Quiznos in Lincoln Park and cooled off in the drink cooler: https://www.youtube.com/watch?v=JWTttvImgnQ
