Wow, that is surprising.  We have had lots of instances of thi problem
where the motorway has a tagged maxspeed which is below normal, and the
link inherits the motorway default.  There, the problem is that link
roads should have a default that is 50-75% (depending on who you ask) of
the non-link default.  That's pretty well agreed on, and I'm not sure
it's fixed.

But in this case, there are explicit tags, and either they are wrong and
should be fixed, or they are right and the route really is good.

I can see the "link road penalty" argument, where I define penalty as an
additional time/distance that *IS NOT* a model of how long it will
really take.  For example, a left turn penalty of 1 minute means to add
a minute for a left turn, above and beyond the amount that waiting and
turning is actually expected to take.

In this case, the map should be fixed, perhaps with maxspeed:advisory
or maxpeed:practical.

Even here in the US where people drive 130 all the time (on roads signed
105!  and they are in the US so they think of it as 80 :), the idea of
130 on a link road seems crazy to me.    I wouldn't epxect that even in
Texas.
