OK, did not see that before, but you are right. That is really a "no go".

No, but I did not care as I selected the bicycle ways.

I also did not notice that Basecamp - unlike MapSource - doesn't allow 
to select the way (car or bicycle), at least I did not find out how,
so it always choses the first way :-(
That makes it likely that the device will also select the wrong type of way.

Conclusion:
- No matter what method we use either car or bicycle routing is not perfect
(this is also true for styles that use continue to create additional ways)
- Until that is solved by Garmin, I agree that we should prefer correct car routing 
and accept detours for bicycles in a general purpose map, so the car road should 
come first.

Attached is version  6 of the patch which is like v5, just reverses the order of ways.

Besides, I would prefer to add a few lines to the default style and remove both
all hard coded make-cycleway options.
