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]
It’d be cool if cyclists could sign up for a program like this. Just a little box on the handlebars that you press a button and it takes and sends a picture
In germany there is weg.li thats is almost as good. It also fills in automatically most of the infos on the cars so you can send the stuff yourself pretty quickly
There’s a website called Bike Lane Uprising that has a database of cars violating bike lanes. Could probably raise millions for cities if they allowed cyclists to report violations.
