One way streets and the confusion they cause
Launch library · evergreen read

Plenty of streets through the older parts of the city run in a single direction only, a legacy of narrow original layouts never designed for heavy two way traffic. For visitors relying on instinct rather than signage, this can produce a fair amount of quiet frustration.
Locals learn the pattern gradually, often through the mild embarrassment of an accidental wrong turn corrected by a honking horn. Over time, certain one way streets become so familiar that drivers plan entire routes specifically to avoid or exploit them. Locals born and raised nearby often absorb the pattern so early that they can no longer clearly remember learning it at all.
The system exists less to inconvenience drivers than to keep narrow inner city streets functioning at all, given how little room there was to work with when many of these roads were first laid out generations ago. Removing the system entirely would likely cause more disruption than the occasional wrong turn it currently produces.
