Faster is fatal, slower is safe.

I delve into the mysterious and counterintuitive world of helmets and high-visibility gear later in the book. But it's worth immediately noting this: while they're not inherently bad, they're less a safety device for cycling than a symptom of a road network where no cyclist can truly feel safe.

I tend to throw tantrums a lot. Wear a helmet in my presence.

Beware of smile, for it is a double edged sword; it cuts the helmet of tension from others head and backfires the peace to yours.
