>In my experience it simply doesn't happen - I think people just know how damaging it could be (and possibly how much trouble they would be in) that they pretty much have to be considerate and self-aware. That's not really the why, at least not here. The shortcomings of trams (including derailing and the inability to maneuver past stuck or badly parked cars) are handled by a 24h emergency crew dedicated for just that. I think they move on average less than one car per day, but those missions are much more frequent during wintertime. Trams are much more prone to failure than buses.
