Some of the advice is based on Hahn’s real-world experience and some of it is unconventional, but it all makes sense and it’s obvious that he’s been thinking a long time about motorcycle riding strategies.
Much of the book revolves around street strategies and risk management.
My feeling is that too many riders don’t think about what they’re doing, don’t have the Zen-like focus necessary to become safe riders and they don’t bother to question their abilities.
Unfortunately, those types will probably never read a book like this or any other that might help them become better riders.
Hahn also explains the famous Hurt study and goes into a lot of detail in Chapter 2 on translating the study’s findings into strategies for safer riding.
