One such report (in German): https://www.rbb24.de/politik/beitrag/2025/10/zebrastreifen-e... in Eberswalde; apparently firefighters were called in to remove the paint but were unsuccessful in their attempts to wash away the white stripes, and police launched an investigation into suspected interference with road traffic.

And another in Dresden: https://www.youtube.com/watch?v=cQUpQZAeA3w https://www.diesachsen.de/en/politics/a-zebra-crossing-in-dr... "In the summer of 2025, unknown individuals painted a crosswalk on the roadway along the busy street in Neustadt to provide safe access to the Heinrich Schütz Conservatory. The city promptly blocked off the crossing with warning cones [...] stating that unauthorized crosswalks constitute not only property damage but also a dangerous interference with traffic. Furthermore, traffic signs installed without authorization constitute an administrative offense under the Road Traffic Code."

In Los Angeles https://www.latimes.com/california/story/2026-10-16/risking-... "Risking arrest, he paints illicit crosswalks across L.A. ‘We can’t wait any longer’" (initially repainting faded crosswalks, rather than creating new ones)
