After driving through a fairly deep puddle yesterday, I immediately heard a noise coming from the underside of my car. I drove the 15 minutes home, and it finally occurred to me that it was the sound of something dragging. Once home, I got down and looked under the front of my car and saw something made of what looked like a fibrous material hanging down at an angle (maybe about a foot wide) and, while I was looking, to my amazement, it retracted. No more dragging, no more noise. Is this some sort of computerized water expulsion feature to let the rainwater out of the lower part of my car? If not, does anyone have any idea what it is?
