There is no special bus routing in the Garmin map format, is there?

I think that we should concentrate on the routing flags that exist in 
the Garmin format.

One thing that may be broken because of this is is 'delivery', 
'emergency' and 'taxi' routing. Does anyone know how these work, and 
have suggestions how to fix this or other special routing?

Not being a Windows or Mac OS X user, the only routing that I can try is 
the one on my Garmin Edge 705. It only supports foot, bicycle, 
car(shortest) and car(fastest) with some avoidance options (unpaved 
roads, major roads, toll roads).

The mofa, moped, horse should be ignored by mkgmap, unless you have 
other rules that depend on them. There could be some strange combination 
of (conflicting) access parameters where your rule works better than 
mine, or where my rule works better than yours. I am open to change the 
rule I committed if I get some examples.
