This was a fun and interesting book club pick. It differed from our normal reads. I liked it because it seemed well researched and provoked thought. I'm not convinced of some of the conclusions, like that we don't need traffic signs, but I was intrigued. Perversely, this made me feel a little better about driving because I'm a real nervous driver, an issue the book doesn't really cover, but it said people are apt to drive worse the more confident and safe they believe themselves to be. I never feel safe, I never feel confident, sometimes just reading about traffic gave me a small anxiety attack.
