...explaining what the riders are doing wrong, and what action they should be taking. That includes recognition of road signs that indicate sharp turns (so slow down). His big three actions are either (a) emergency braking, (b) emergency swerving, or (c) emergency accelerating to escape the hazard. Most of the time there is excess speed involved. I also don't understand why riders are "lane splitting" at fairly high speed with stopped or very slow traffic. Talking ~50 mph driving through and by slow/stopped traffic.
