We all have different expectations from reporting things to the police and if you are satisfied with the actions taken then I respect that.

I've been cycling for ~45 years and commuting by bike for about 20 years. I've experienced every variation of bad driving there is, including two hit & runs and an assault by a passenger leaning out of the window of a dangerously driven car. It was primarily the crap police response to the assault that convinced me to start using a camera.
Despite that, I have a deep respect for the police and I know how poorly resourced and overstretched they are. It is for that reason that I don't report every piece of careless driving that comes my way, I save involving the police for incidents that put me at real risk of harm. Having this high threshold of reporting means that, for those I do report, I expect a prosecution or a fixed penalty to follow.
In the 8 or so years since first getting a camera, and of the many hundreds of episodes of bad driving around me, I have reported a total of three incidents to the police:
First was a close pass, rejected initially by a young cop who wasn't interested; the car didn't hit me so he couldn't see the problem. Insistence on a face to face meeting with him and his supervisor resulted in the driver getting a £100 FPN and 3 points.
Second was a left hook which the police immediately acted upon and charged the driver. They did, however, try to steer me towards approving a driver awareness course but I said I preferred prosecution or at the very least a £100 FPN plus points. I'm still waiting to hear which route they chose.
Third was a close pass just last week. Police agree it was a S3 offence and will interview the driver. I'm waiting for them to try to convince me that a warning will suffice when they find the driver is a little old white-haired lady in her 70s.
I hope the above explains why I wouldn't regard the outcomes of your incidents a success.
