[Routing] Leave motorway, turn onto track

[Frederik Ramm]

Hi,

    it is not uncommon in Germany for a track (highway=track) to be  
connected to a motorway in such a fashon that you could theoretically  
turn onto the track from the motorway if you were travelling at 10  
mph or so.

It isn't allowed of course, and that should perhaps be modelled  
through appropriate turn restrictions.

I wonder if it would nevertheless make sense for routing engines to  
implicitly disallow leaving a motorway on anything else than a  
motorway_link (or at least not on something as small as a track).

Here's an example (where the route leaves the motorway in the north):

flat=49.016459&flon=8.456449&tlat=49.089696&tlon=8.546314&v=motorcar&fas 
t=1&layer=mapnik

Bye
Frederik
