If anyone can jump in, I liked the Chekov's Gun of how the car decides what counts a person. That was inserted smoothly enough that I didn't wonder at the time of reading it if that information was going to turn out to be relevant towards the end.
You could argue that grandparent's criticism was presented as the more objective 'poorly written', which suggests a lack of skill on the author's part. Whereas the parent seems to address the style of writing, which is more subjective and less demanding of citation.
I actually quite enjoyed the writing.
