[GraphHopper] routing problem

Hello,
I did some routing tests on http://graphhopper.com/maps. Long distance  
routing seems to be very comparable to other routing services on the net,  
but way faster.

In short distance routing I found a problem with a query in my area:
http://graphhopper.com/maps/?point=wehlener str. 1%2C  
dresden&point=alttolkewitz. 1%2C dresden&vehicle=CAR
The resulting route over An der Rennbahn is only the third best route,  
there is also a direct road connection from Wehlener Str. to Alttolkewitz  
(first best route). The second best connection would be over Bodenbacher  
Straße/Pirnaer Landstraße.

I thought the result could be not optimal, because Graphhopper relies on  
(maybe incomplete?) Openstreetmap-Data but if I test the same locations in
http://openrouteservice.org/index.php?start=13.8267204,51.033242&end=13.8305277,51.031594&pref=Fastest&lang=de  
the shortest route is calculated.


greetings Konrad
