I've stopped applying rules to walkers now because their behaviour has been pretty inconsistent over the years. They used to be able to open doors, but they don't seem to anymore.
At other times they appear to wander impassively when not near living people, whereas other times they're hammering down doors despite there being no sound on the other side (see Fear The Walking Dead for an example of this).
Not to mention the fact surely a lot of them would have simply starved to death by now.
