In Amsterdam the tram is 57x more deathly than the car.

Trams in Amsterdam should be replaced with busses. Busses stop much faster and don't weigh as much. Trams are literal death machines. It's really scary to ride bicycle in Amsterdam and hear the ding-ding-ding when you are about to be run over by a tram and you quickly have to move over.

Also you seem to be a bit confused, Amsterdam does not use narrow cobbled streets for traffic calming. Maybe you are thinking of France or Belgium.
