Can confirm, bears can definitely adapt to being around humans and be used to their presence. Lived in a tourist town that had a massive amount of black bears and I’ve literally been close enough to pet one after going around a corner, we startled eachother for sure, sat and stared for a second, and then calmly backed away and went our merry way. I don’t think I’ve ever heard of a bear attack there, and it’s literally where the story of cocaine bear came from and is filled with incredibly dumb tourists.
