Helsinki is not that bicycle-friendly at all. More space for bicycles on the roads would help a lot more than a route planner. It is good progress, I don't deny that, but it certainly doesn't make Helsinki the most bicycle-friendly city in the world. Amsterdam and Copenhagen are probably years ahead of Helsinki.
Boston is also quite good. An avid cyclist friend in SF was very jealous of our minuteman trail. I certainly love it, and there is talk of extending it all the way downtown.
