[mkgmap-dev] Incorrect runabout exit indication

The new styles for Lambertus you can find here:

The issue could be that there are two lines used for roundabouts:


First step, an invisible routable line for the roundabouts 0x0c

# Roundabouts
junction=roundabout & highway=trunk [0x0c road_class=3 road_speed=2 resolution 18 continue with_actions]
junction=roundabout & highway=primary [0x0c road_class=3 road_speed=2 resolution 19 continue with_actions]
junction=roundabout & highway=secondary [0x0c road_class=2 road_speed=2 resolution 20 continue with_actions]
junction=roundabout & highway=tertiary [0x0c road_class=1 road_speed=1 resolution 21 continue with_actions]
junction=roundabout & highway=unclassified [0x0c road_class=1 road_speed=1 resolution 21 continue with_actions]
junction=roundabout & !(highway=unclassified|highway=tertiary|highway=secondary|highway=primary| highway=trunk) [0x0c road_class=0 road_speed=1 resolution 22 continue with_actions]

Second step, all roundabouts are made unaccessible after 0x0c is processed, in order to prevent two routable lines on top of each other:

junction=roundabout {set access=no}

Third step (continue with_actions) the highways are rendered, so you can see a difference in road classes on those roundabouts.
The default mkgmap style (=Lambertus 'old style') renders all roundabouts the same.

I think Johan's nuvi gets confused by those two routable types?
