I think that is the reason why we sould stick with explicit turn restrictions. 

The law on solid lines varies from country to country, and we cannot expect the routers to code, or know the law for every country, mappers on the ground will be aware of the restrictions however.

In Germany that's not the case.
You're not allowed to cross a solid line.

If you're allowed, the line is dotted for the small part where you are 
allowed (or a second dotted line on the side where you come from is added).
As overtaking has to be finished before the dotted part of the line 
ends, even that's not allowed by a part of the line being dotted to 
allow a left turn towards an access ramp to a building or sth. like that.
