Query: immortal class. ok

Here's what you learn from this book: as a class, bicyclists have about the strongest sense of anyone of their own moral superiority despite the fact that they are as incosiderate in public spaces as just about anyone, and, as a class, bicycle messengers are like bicyclists in general but even further convinced of their own cosmic significance and worth, and they are even less considerate of others. You learn that no one on a bike has ever done anything wrong, and that though messengers serve corporate America, they are, through some bizarre twisting of facts in their heads, actually undermining capitalism, saving the poor, and generally spreading enlightnement. You just can't help but wonder whether the words can be found to praise them as highly as they deserve. But don't take my word for it, check out the review from a customer with all the quotes from the book and then decide.
