I ride both motorcycles and scooters. I'm not an ATGATT guy myself and I don't believe there are too many true ATGATT riders out there. If you are not wearing racing leathers and top of the line boots and gloves, you are compromising protection to some extent. What I wear depends on the ride and the weather. I may ride around the nieghborhood after washing a bike on a hot day in helmet, gloves, shorts and T shirt. Going to the store I'll wear Helmet, jacket gloves and jeans.
I was at Deals Gap last weekend. Most of the motorcycle riders there were not wearing much protective gear (mostly Harleys & touring bikes) I was riding with my wife on my scooter. We had on more gear than the Majority of the motorcycle riders.
