Cyclist Andreas Mandalka, 43, was killed by a car in Baden-Württemberg two weeks ago. Police are investigating a 77-year-old driver on suspicion of negligent homicide.

On Sunday, 500 cyclists gathered in Pforzheim for a memorial ride to remember Mandalk a. He was known for his videos in which he captured drivers' risky overtaking maneuvers and exposed them on social media. He sometimes faced headwinds for his bitter resistance to such rough driving behavior.
