They have several warning displays scattered through the exhibits at Yosemite that are the remnants of car doors 'opened' by bears going after goodies left in cars. Most involve the window frames pried away at 90° to let them get a better grip on the door to essentially tear it off of the car. All casual like, from the footage they've captured; just walking up and opening it like you or I would open it normally. In her case it was probably better to leave the door open! At least it doesn't have to be replaced now.
