An interdisciplinary team of journalists, physicists and machine learning experts developed an app and a sensor to measure whether cars keep enough distance to cyclists in the city, according to official standards. 2500 readers volunteered to help gather relevant data in Berlin. The result is an interactive story guiding readers through large amounts of data in a playful manner. 

Tagesspiegel Radmesser was awarded with the German Reporterpreis 2018 for data-journalism and a nominee for the European Press Prize and Henri Nannen Preis 2019.
