The problem with that theory is that you never know what kind of lock the guy next to you is going to bring with him.
Honestly, I seldom use any lock on my bike. It's unusual for the folks that I ride with to use one either. Somewhere down in my bike room I have a 15 year old Kryptonite U-lock still in it's box. I'm glad that I live where I do.
