Good to know: Return or one way?

You know how it goes, you’re finally planning on leaving town, maybe for a a concert in Bern or Basel, but you give up because the latest train back leaves too early. Or takes a route through every small town on the way. Mobility is your answer. They just launched their one way service where you can book a car to and from the main stations in Basel, Bern, Lucerne, Solothurn and Zurich (main station, Altstetten and airport). There you just leave the car and walk or cycle the rest of your way home. The additional fee is 29 francs, which I find fair enough.
