The trams and tram tracks in Amsterdam is still a problem for bicycles. Cross the tracks wrong and your bike tire gets stuck in the tracks and you go head first in to the street. Trams themselves can be as deadly as cars are to bicyclists. Fortunately they are more predictable and confined to their tracks.

Ideally, both trams and cars would be completely underground or above-ground, and have no possibility of collision with bicycles or pedestrians at all.
