Germany has a strong heritage of industrial typefaces. These fonts seem like being constructed by engineers.

The shapes seem to be built with circles and squares. DIN Mittelschrift is one very famous example, or the font on the old German car number plates. Since the Romain du Roi we know that it is tricky to draw a geometrical typeface. For optical reasons you have to go away from circles and lines with exactly one weight.

Therefore the aim is not to construct a typeface but to draw it the way it seems constructed finally. The design of a typeface is like stage production. Like heavily made up actors the characters of a typeface must be exaggerated to work well. Particularly in small sizes.
