Thanks a lot for that info.

I agree that it doesn't really matter which way gets used as they share
the same nodes but if you take away bicycle access from the road, the
gps will tell you to route via "Foo (cycleway)" rather than "Foo". It
seems to me that would be more consistent and at least in some
countries it would agree with what is the normal behaviour. I'm tempted
to add:

  if(currentWay.getTag("bicycle") == null)
    currentWay.addTag("bicycle", "no");

so that if the original way doesn't already have the bicycle routing
defined, it will be disallowed.
