You did not fetch my issue. There is no debate which way gets which maxspeed tag. There is an ambiguity which way is which type.
Is a path per default a footway or is it a cycleway? When there is no explicit tag, which decision is right? In Switzerland it may happen that a primary route crosses a town. That does not mean that a speed limit other than the default for primary routes is valid. There _has_ to be a traffic sign. Different countries, differing rules. We need to get a standard way to address this. And a routing algorithm could take into account that a primary road crossing a town cannot be used driving at maxspeed. Think of a hiking path that crosses a country border. Think of the rider of a mountainbike. Which access restriction is in effect? Where does the situation change? Will every mapper be foresightetd enough to explicitly tag the way correctly? Exactly at the border? The case of a residential road is easy for us Euopeans. Have a look on the US defaults. They change at the state borders. Whether that has a meaning or not I cannot tell. Depends on the local situation, I think.
