I've read it. I did a longer review at Amazon.com, but briefly, here's what I think:
Hurst wants to teach you to ride like a bike messenger. That's cool if you want to ride like a bike messenger, but it does absolutely nothing to help normal people learn how to bike. It's like a cookbook written for pro chefs, which assumes that you'll be getting into a commercial kitchen and cooking spectacular special meals, when what most people need is a cookbook that'll teach them how to cook something fast, simple, and healthy at home. He's ultimately a lot like Forester: he thinks the way the roads are now is the way they ought to be, and he's not really interested in people who don't identify themselves as cyclists. Status quo.
That said, he's got a lot of good observations and advice for those who want to ride in an intense, hard-core style. I just don't see my mom -- or most people -- wanting to do that. And we won't get a bike culture in this country until my mom feels comfortable out there.
