The data I can find doesn't support the assertion.
> In the period between 2019 and 2022, 1,199 cyclists were killed in traffic accidents, with 42 percent of these accidents being caused by collisions with a passenger car or van.
Here is says that indeed cbs doesn't track it and that there were 21 deaths per year caused by trams, buses and trains, with 57% of those pedestrian or cyclist
this ad-article "Jaarlijks worden er om en nabij 150 personen behandeld in een ziekenhuis na een aanrijding met een tram en komen er zelfs 40 personen te overlijden na een tramongeval." - I think what they mean is 40 people in a decade?
