Similar to "Street names don't recur" -
A named road will be continuous: a friend lives in a condominium,
in one of a group of 8 buildings bounded by 3 fairly normal roads.
There are 4 separate driveways between buildings leading to parking.
At some point the condo units were renumbered with street numbers,
and the disjoint driveways were all given the same name: <Condo> Lane.
Regular delivery drivers - USPS, UPS, FedEx, and pizza seem to cope,
but taxi drivers or other irregular visitors who expect numbers
to be continuous along streets are almost always baffled.
Similar to "A road will only have one name",
for emergency services - fire, ambulance, and police - a similar
case arises when a route passes through several small towns, each
with its own set of street numbers, possibly with variations of proper
street name, and perhaps with different direction/cardinality mappings.
For a motorist calling 911, reporting that one is at street number
123 on El Camino Real (on the SF peninsula) will probably map to
several possible locations, depending which of the 12 or so towns
one is in.
