Helsinki’s personalized bus service is like Uber for public transit 
Now <i>this</i> is interesting, when compared to Uber and the like. I imagine it requires a large ridership to be worthwhile (otherwise you're basically dispatching large cabs, but charging less), but it's a fascinating concept for large cities.<p>I imagine there are downsides though - if you're using it to get to work then surely your journey time is variable?
