Unfortunately something similar¹ happened in Germany as well (2024):

¹ similar in the sense of "cycling activist was killed by car-brain"

Starting in 2011, Andreas Mandalka wrote on his blog under the pseudonym Natenom [...] about the dangers cyclists face from motorists, particularly in the area around the city of Pforzheim. According to his own account, he often cycled between 50 and 80 kilometers a day. His reports focused on unsecured bike paths, motor vehicles failing to maintain a safe distance when passing cyclists, as well as the inaction of authorities and the lack of prosecution when such violations were reported.

Mandalka was killed in a traffic accident on the evening of January 30, 2024, on State Road L 574 between Neuhausen and Schellbronn. In the dark and on a wet road, a 77-year-old man struck Mandalka from behind with his car while he was riding his bicycle; Mandalka was wearing a helmet and a safety vest at the time of the accident. Mandalka died at the scene of the accident. He was 43 years old.

For years, Mandalka had documented the dangers of the state highway [L 574] on his blog.
