Don't know how that works out in Finland, but there are a few of those in Paris, and while they are just as good as those on the street at certain hours, at other hours they become overrun with inattentive pedestrians that confuse them for a sidewalk. This makes those lanes dangerous for both cyclists and pedestrians as a result, and very slow for cyclists compared to a regular bike lane. A third to a half of the cyclists opt for the bus lane instead (despite it being forbidden to cyclists). And they are not slowing the traffic. In fact, cyclists move faster than cars at the particular location I have in mind.
