Well worth reading (particularly if you're unfamiliar with the general bicycle advocacy literature - or for that matter, the literature that painstakingly lays out the pathologies of our self-destructive car-obsessed-and-dependent-and-biased culture/economy/society).
This is a highly accessible, easy to digest introduction to many of the larger issues currently being addressed (or, frankly, ignored) at the federal, state, regional, and municipal level after years of under-investment in infrastructure (and, of course, the potentially significant coming investment in (hopefully reimagined) infrastructure) and will become only more prevalent as the accelerating climate crisis drives governments and communities to think further outside the box.
Special kudos to Blue for being ahead of the curve and getting the research, literature, anecdotes, ... and stories out into (or at least closer to) the mainstream years ago (even if I only recently actually bought the updated/expanded book).
Minor Nit: As convincing as Blue's thesis (and larger storyline) is (are), don't expect this to read like a conventional economics argument. All the pieces are there, but (best I can tell) Blue isn't writing as an economist or for economists - and that's OK - but the title might suggest otherwise, at least to some.
Reviewer's Achilles Heel/soft-spot: This won't come as a surprise to readers well versed in the modern literature related to climate change, environmental justice, and, well, advocacy related to almost every conceivable pathology in modern society, but ... if you're an older, white male (and, even more so, if you're economically well off), even if you're a bicycle advocate, well ... you're not the hero of this story and, more specifically, you're (pretty consistently) billed as the problem (or an impediment) rather than the solution. Of course, the maddening thing is that the author is right - she's spot on (and clear in her explanations as to why).... But it does make the reading experience somewhat less pleasant. (Ah, the proverbial dose or reality, eh? ... Alas.)
p.s. The book is highly anecdote-driven, so (based on my own, albeit quirky, experiences) I was ever so slightly disappointed that I didn't find any/more references to some of the really impressive infrastructure development and urban decision-making related to bicycling in Denver or Geneva (Switzerland). Maybe they'll make it into the next edition, in addition to a stronger climate-change mitigation hook, along with more coverage of the explosion in e-bikes - for personal use, for older riders, for freight delivery, and, of course, for the Uber-Eats/GrubHub-type market.
It sure seems like the time is ripe for another, newer, further-expanded edition.
