If you want to turn right here http://www.openstreetmap.org/edit?editor=id&way=217346325#map=18/53.87405/8.67926 from Feldweg into Döser Feldweg, MF Navigator asks you to go straight. In reality you will end up into that section where you are later forced to left, so into the opposite direction you want actually want to. Wouldn't it be better to have the command here to "keep right"?
The problem is not MNF but OSM in this case. This cross-section has turn-restrictions where it directs you straight-forward "Feldweg to Feldweg", instead of to the right "Feldweg to Döser Feldweg".

I have no idea how it really is setup overthere so I can't and will not change it. Someone with local knowledge should check whether the turn restrictions are setup correctly.
But that's exactly what we mean: Because of this "only_straight_on" relation, MNF does move you straight on to the junction instead of directing you from the "Feldweg" onto the right ramp "Döser Feldweg" and then onto the "Döser Feldweg" going North. Using the ramp is much better then driving up to the traffic light only allowing you to go left. That's incorrect mappiing. Currently the turn restriction is:
^
|
instead of
^ ^
|/
w.r.t. to the turn:lanes :they do nothing for the navigation. If properly programmed (currently a bug I think) they only provide arrows for lanes in the top of the screen.
No, you misinterpret the relation. It says if your are on this way (from) you can only go here (to). There is no restriction (from) if you are on this way.
So we ask again, why Navigator says go straight. This is even more strange if you consider, how the ways are designed in OSM. There is a rather sharp right turn, where Navigation says straight but shows to follow the way on the right side.
