This is a fabulous graphic novel that takes place while the protagonist Alex is sitting in LA freeway traffic, although occasionally the traffic does move, while he thinks back to his life - how it's unfolded from his childhood, and even how his life might have played out in an idealized, dreamlike LA of yore.
There are many strands woven together, these are more than flashbacks, they are what comprises Alex's life - his obsessions/worries as he waits in traffic. His life is playing out while he waits - and the stories explain what he is worrying about, or thinking about, or fantasizing about. That's an extremely simplified way of describing how the book works.. actually, the book can be read very quickly, rather than my trying to explain or describe the flashbacks and so forth, a reader can read the book and see for themselves.
I enjoyed the stripped-down drawing style - and the dialogue/characterizations were immediately understandable. The protagonist was highly nuanced, and the book draws you into his anguish at being stuck in traffic, and yearning for an earlier era in LA, when there were fewer cars, an era of perhaps more elegance. Or what we might think was a more stylized, formal era - maybe since we mostly know of it as depicted in motion pictures of that time, which do not necessarily show how the majority of people actually lived. Still, we can get an idea of how most people lived in the 1940s or 1950s even looking at old family photos (or, sometimes, movies). There were tens of millions less people in the US in those days - there was less crowding, there were undoubtedly fewer cars. Also, the US might have become more urbanized anyway - these trends, of increasing population and urbanization - ended up leading to the traffic jams, unending cars in LA.
There is also one sequence though of Alex taking mass transit home, from an outlying area - which consists of light rail, running alongside a freeway at times. There is more mass transit now - he remembers the past & lost era of streetcars in LA. The juxtaposition of his present misery sitting in traffic vs. the past seemingly more "glorious" time, is just one of the "heartbreaking" subtexts in the book. There is so much heartbreak - which makes the book so compelling. He's "fated" seemingly to never make it. His affair with a co-worker comes to naught, because of her responsibilities to her parents/family; that's contrasted with the family his earlier "alter ego" "incarnation" develops - marriage, kid, home, etc. The entire book is an homage to how fate somehow conspires to screw him - recurring fantasy/"paranoid" sequences of disasters that might befall the driven are woven into the narrative. I won't give away the final "catastrophe" - suffice it to say that the book winds up on an exceedingly powerful note, possibly yet another fantasy, but we know the story is over with the vacated seat in front of the TV he used to watch as a kid.
I think this book must resonate with many since it describes the typical arc of life: Idealism, high hopes - with career, relationships, and so forth - which gives way to disillusionment, heartbreak, despite the protagonist being a nice guy, things do not go his way. He is essentially driven crazy by circumstance - a crazy boss, a love affair that sputters because his girlfriend's parents take precedence over him, the general anonymity/vastness of LA finally crushing him; several ways of escaping his misery are described, but it's never clear if they are mostly fantasies, or if he has really finally given up on trying to make it in LA. Isn't this what life does to most of us: Turns us from "happy campers" into "haunted/paranoid losers" or something along those lines? Isn't this why most readers will easily identify with the transformation Alex undergoes, as he lives out his life, or recollects his life as he sits in freeway traffic.
