That is Garmin behaviour indeed. Sometimes it also sticks to thinking 
you're driving on a sidewalk (footway) which leads to funny behaviour 
like routing failing.

I use TYP files. I've solved that by using a non-routable line type (ie. 
not the normal 0x15/0x16) for cycleways and footways. This prevents 
Garmin from thinking you might be on them. (Yes, this has side effects, 
if you do that for a car routable cycleway, for example one with 
motorcar=destination). In my TYP file I have two similar looking lines, 
one that is normal routable and another non-routable.

Unfortunately this means I have to compile another map without the tweak 
for cycling/walking.
