Always amused by HN on buses. It seems that the median HN is basically okay with trains, but is convinced that if they ever set foot on a bus they will immediately be stabbed by 47 drug addicts, and then their soul consigned to Bus Hell. It's kind of comically hyperbolic.
I wonder where the dividing line is. Are HNs afraid of trams? Very Light Rail systems? Trambuses? Trolleybuses? BRTs? Railbuses? Someone should do a survey.
