Why is it so rare for authors to include a summary, outline, diagram, or map at the beginning of each chapter in a book, to help readers locate themselves in the flow? Only example I can think of is N. Taleb's micro-summaries of each chapter. Any good examples you can show me?

Interrupts flow and weakens implicit structure. Think free weights versus machines. I really dislike books that do that unless they are literal textbooks with non-trivial technical exercises at the ends of chapters.
