Interesting. I'm in the middle of this book now.
My take so far is that Hurst departs from VC insofar as it has become an ideological fixation for some. In other words, taking the lane is reasonable in some cases, but not in others (e.g., high speed, heavy traffic). He does seem to caricaturize VCists as those who are *always* opposed to bike lanes, and taking the lane under *all* conditions. I don't recall if I've seen the word "invisible cycling", but it seems a lot like what I was taught as an automobile driver in my youth when it was called "defensive driving" -- that you just can't rely on all motorists to comply with all the rules of the road all the time. I would call him "pragmatic".
He does have a good sense of humor, but I'm not all that impressed so far. I was really looking to find something that went in depth into VC and all of its subtle implications.
