There's always the people who always show up in WMATA threads and say "I simply plan my entire life around assiduously checking Metro timetables and apps so that I don't arrive at the station at the incorrect time" as if either option is sufficiently accurate to begin with, not to mention that the only way to get people to take transit rather than drive is to make it something you don't have to plan your plans around because the headways are short.

And yeah, before someone says that my sarcastic remark doesn't match their experience of using apps or whatever: you simply shouldn't have to know this, you should be able to walk into a metro station and get on a train in short order, not after a quarter of an hour of waiting in the dark caverns.
