This is mainly just me trying to make something sad and melodramatic. The comic is not supposed to be some sort of summary of modern life but rather an intentionally sad and sentimental rendition of it, depicting some of the bad parts. In fact, post-industrial life certainly seems a lot better than industrial or pre-industrial life. But still there are some issues that are very particular to our time and culture, and this comic shows a couple instances of this.
Also, the fact that the mode of transportation changes throughout the comic is not accidental. Hint hint.
