We currently recognise the toll=yes tag and set some bit of state in
the map file but whether that actually has the desired effect, I do not
know.

> Unapved Roads
> Carpool Lanes

At this time, we don't know how to express those attributes in the
garmin file.

> Highways

Well, on my Etrex I can tell it to avoid highways when routing and it
will not use any primary or trunk road (don't know about motorways as
none are near to my cycling area).

Why can't you just tell the GPS to route for bicycle (rather than car)?
It will then respect the bicycle=no restriction.

Sorry, I don't know about that issue.
