SF solves this by putting cameras on the busses themselves. Bus driver sees someone blocking the bus stop or bus lane, presses a button and creates a ticket.

You get a live witness, video footage and only enforcing it when a bus needs that space.

It works too, uber drivers do not like picking up people in bus stops.

You could extended it to citizen cyclists too with some political controversy.

I would love to be able to write tickets on cars illegally parked in bike lanes. Give me a ticket book and I'll work for free. I'll even document every ticket with unimpeachable timestamped video footage.

In some German cities you can email the police a photo along with a description when and where the infraction took place and they will issue a ticket. In other cities you might have to mail it the old-fashioned way.

We've got apps for this in NYC that issues enforcement and TLC driver complaints through the 311 system, and I use 'em.
