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]
In Germany you only have to use a crosswalk, if it is within 30m of where you want to cross, or 40m in case of a traffic light. Otherwise you can cross wherever you want. Obviously you got to do so in a safe manner.
