The above video offers what I hope is an extreme example of street
number craziness in the UK (a street with multiple number "2"s,
etc..). I gather there is similar messiness in parts of Asia, like
street numbers assigned based on the age of the building...

The best arrangement I have seen for street numbers is in Chicago, IL.
Streets laid out on a grid pattern. On the north/south and east/west
streets there is a number -> distance link. If you go from say 1 North
Michigan to 801 North Michigan you will have travelled ~ 1 mile (or if
you go from 1 to 501 you will have travelled ~ 1 kilometer).

Toronto, Ontario things are almost as good. Almost all north/south
street are have the lowest number at the most southern part of the
street (Toronto being unable to go any further south due to Lake
Ontario). On east/west streets the lowest number is almost always the
point closest to Yonge St. (a major north/south street). What Toronto
doesn't have but Chicago does is the link between street numbers and
