ATG: Helmet, gloves, boots, jeans, jacket, glasses/visor
That's my understanding at least, and if I'm going around the block or doing a short commute (sub 40mph) to work that's what my gear consists of and I adjust my riding style to reflect that. If I want to play around, get out of town, etc I'll be sure to wear a ballistic jacket and pants, armored riding boots, armored gloves, full face helmet, and I'll throw in an extra layer of warm clothes in the side cases. There is always more or better gear to wear, and there is always someone who is just a little safer then you gasping at your poor safety choices. So unless I see someone in shorts, flip flops, or a novelty helmet I try not to judge.
