The stopping distance is more than twice as long as for a bus[1], so this actually makes sense. [1] https://www.edinburghnews.scotsman.com/news/transport/trams

  I had this thought, so it is interesting that it is confirmed elsewhere. I don't know if it always plays into the fact that the trams in Oslo are actually old (according to Wikipedia, from the 80s: https://en.wikipedia.org/wiki/Trams_in_Oslo https://en.wikipedia.org/wiki/Trams_in_Oslo)

    I think it's pure physics. Trams are much heavier than buses so there would be more mass to be stopped. In addition I think that vehicles running on tracks take longer to stop. I live in Zurich, which runs overall pretty new(ish) trams. Makes no difference. Disclaimer: I was always pretty crap in physics :)

      The coefficient of friction of rubber on road is much higher than steel on steel.

        Which is why trams that go up and down hills use rubber rather than steel (like one in Lausanne).
