The big issue with curiosity in something as large as bears, moose, zebras, giraffes, etc is that they’re big enough to significantly damage your car if they decide to try to get in or get annoyed, let alone a person standing unprotected. Some of the funniest bear videos I’ve seen are clearly cases where the bear just said, “wow, that’s a big tin can with an interesting shiny inside, let me grab this bumper thing with my teeth to unwrap the tin can .” :-)

The infamous Siegfried & Roy incident with Manticore the lion demonstrated pretty effectively that wild animals be doin’ wild things, and even when trained like these bears are wise handlers remember that they aren’t predictable. If nothing else, the chicken wire/bear wire is a great early warning system- if the bear starts fixating on getting through it it’s time to figure out how to subdue it.
