In retrospect, a lot of Fahrenheit 451 seems like "cranky old man" territory, although Bradbury was only 33 when it was published. I recall a lengthy passage where Clarisse talks about how highways have destroyed respect for nature because it's impossible to see flowers at freeway speeds. Literally impossible, this wasn't just a metaphor--she also mentions how freeway advertisements have to be extremely long because ordinary billboards would just be a blur, which implies that Bradbury had never actually ridden on a freeway before despising them.
