I've seen maybe one in the past two months. Most of the riders in my area are on cruisers and most wear a brain bucket and little else safety-wise. The guys/girls on sportbikes always have a full-faced helmet and t-shirt, no gloves, jeans or shorts, and sneakers. None appear too bright and when I see them they just look odd. I don't have full leathers, just my helmet, gloves, a good leather riding jacket with the protection plates, jeans, and safety boots.
Agreed on the "worst driver" comment. My brother wears leather shoes that cover his ankles, gloves, and a helmet, with a two-piece suit. When we went riding he asked me if I planned to fall, I told him no, but I don't plan on being sideswiped either but why take the chance. I think the cops around here would probably look extra-hard and just might even pull guys in full leathers for the slightest infraction
