UNSOLVED MMM-GoogleMapsTraffic: Increase level of detail

[drfukc]

Hi all,
I feel quite happy with my Google Maps Traffic module but would like to increase the level of map details.
Some streets do not show, they are not displayed due to the zoom level.

Question:
Is there any (hidden?) trigger I can use to modify the level of details without changing the map-size or zoom-level?
