I couldn’t find an English language source, so here are some excerpts from the German one, translated with deepl [Stuff in brackets are additions by me]:
Wiesbanden bus driver Antonio Lopes recently got a yellow button next to his steering wheel: if he sees a parking offender blocking the bus lane or a bus stop, he can trigger the front camera. […] The images are sent to the traffic authorities. Drivers face a fine of around 70 euros. If they park in an environmental lane that is only intended for buses and bicycles, they will also receive a point in Flensburg. [Collect too many points and you loose your drivers licence]
My city has an app for submitting traffic complaints that automatically grabs your location and asks for a photo of the offending vehicle and plate - and they’ve actually followed-up by sending people to confirm the violation and issue tickets. I’ve reported so many stupid trucks parked in bike lanes and motorcycles parked on sidewalks lol - carbrains are so obsessed with driving but can’t seem to do it properly ¯_(ツ)_/¯
