In Switzerland the so-called “Post buses” (the yellow buses) are kind of a national institution!
And, as all the other kinds of institutions in the Confederation, they are part of the Swiss pride.
There is a nice App to know all the possible timetables and live schedule changes of these buses. Nowadays this is comon for every public mean of transportation.

Last week I was waiting for my usual post bus No. 354 at 7:54 in the morning to go to the office, from the remote village of Ehrendingen to the more remote village of Niederweningen, crossing the “border” between canton Argovia and canton Zurich… An amazing trip in the fields which is normally taking 6 minutes.
1 minute after the scheduled time… no bus was arriving
2 minutes after the scheduled time… nothing
3 minutes after the scheduled time… nothing
…
…
Then I thought: let’s check the wonderful “post bus” App!
The result was astonishing: For a 6 minutes’ trip, a (very well) announced delay of 7 minutes was displayed on my App!

Confederate trains and buses are always on time?
Ehm… actually not!

But the delay is so precise as nowhere else!
