Why are there CAUTION signs on automatic doors?

The fine print should say "Carefully walk through this door way in any fashion you choose. Doesn't matter. The door will open automatically anyway. So, uh, you know... be careful."

Also if it is one of those doors that swings open by the time I am close enough to read the sign the door has already opened. So if the warning is about it hitting me in the face,by the time i have seen the sign the door has already hit me in the face. Thanks.
