Yup, use the buses, trams and trains all the time. It was quite nice going out to our triathlon on Sunday and seeing loads of triathletes on the S-bahn. We aren't allowed to take bikes on busses or trams here and are restricted to off-peak times on the U- and S-bahn (underground and city railways respectively), but that is understandable.

In fact, DH and I said the other day that we should go and check whether our car was still in the garage - we hadn't used it for a few weeks and we could imagine what the police would say if it got stolen: "so when did your car disappear?" us:"umm, some time in the last six weeks...."
