You don't stop dead-cold because a corner comes NEAR you.
Most doors are fine, but there are a few that suck. Usually the trouble is a pocket door that doesn't open fully, and doesn't have a player clip that captures the door in the open postion, so you have a four-inch wall that will block you if you don't hit the hole centered. With an appropriate player clip, you won't need to strafe around it, since if you are at least looking away from it, the angled player clip will guide you into the opening.
I seem to be pretty good at not being stopped cold by brushing against an object. Usually it goes in the space under my arm, or my body gets angry and knocks the object out of the way. In rare cases, my spine will contort and maneuver around the object so momentum can be preserved at the cost of a slight and temporary balance reduction.
