This is a well-considered manifesto about the absurdity of allowing bike racing culture to dominate the thinking of the everyday bike rider. I can see how this little book would upset a lot of the high priests and acolytes of the bicycle world, but for the rest of us, it's a good, common-sense guide. Ride in everyday clothes, carbon fiber works for racers but can fail spectacularly and suddenly for everyone else, exercise doesn't help you lose weight, use steady lights instead of blinkers, baskets are a good thing, etc. You won't necessarily agree with everything Petersen says, and that's fine. Take what works for you.
