Sorry, but your interpretation is wrong in my opinion - and "too 
literally translated".
"destination" can not be used as "you want to drive there" but as "you 
are allowed to drive there"
As in
- german Anliegerverkehr
- swiss Zubringerverkehr
- austrian Anrainerverkehr

Yes - but that's the very rare edge case Simon wrote about.
Try to think about a router that would be able to handle this case - and 
its preconditions.
