I disagree. I have recognized people from across a busy park and on the street based on their gait, known it was them long before I could make out any other recognizable trait. It's like your typing fist, or handwriting recognition: can be beat, but it's tough. I've conscientiously tried to change my gait and walking style, and I think it's kind of hard to do (I can still feel the distinctive elements of my gait coming through). It would be an interesting experiment to try to beat this.
