Border cutoffs not accurate

A lot of roads on the Latvian side of the border with Estonia are marked as Estonian.

Most of Monaco's roads are marked as French. A very small part of Monaco is marked properly.

Spanish data cuts off 2KM before Gibraltar leaving almost no data for La Línea de la Concepción.

Roads well inside of Spain are marked as Portuguese.

Austria, Liechtenstein and Switzerland all have overlapping issues.

There is a stepping pattern from the French side as it overlaps much of western Switzerland.

Luxemburg and its neighbors.

I noticed the same in Benin border region. I was surprised.

@marklit @Skerre You are correct. Mapping roads with a CountryCode is not perfect near countries' borders.

Roads are assigned CountryCodes based on quadkeys they cross
