Please report dangerous drivers to the police - Roadsafe. Report to plod, not just whinge here.

Was punish-passed a couple of weeks ago when riding with a friend. I'd filtered in front of the guy at some lights, despite him practically going up on the kerb to prevent me coming down the cycle lane into the ASL box. After the lights went green and we moved off, the driver drove at me - his car was angled towards the side of the road as he came past me a couple of inches from my front wheel. I was half expecting it so managed to slam on the brakes and avoid him. He then brake-checked my friend and I multiple times before we just stopped to let him drive off.

I wasn't recording video but got a photo of the guy's car and his number plate. Reported to the Met without evidence, knowing that he definitely wouldn't get charged with anything but thought he might at least get a warning.

I've just been told "this case was closed as there was no video footage or no independent witnesses to support your allegation so we are unable to pursue the matter". To which I asked what I'm supposed to do the next time someone tries to kill me with their car if I don't have a video? And if I'd reported someone attacking me with a knife, would they also need video evidence of that?

Their reply:

You would need an independent witness who witnessed the incident and who is willing to go to court to be a witness if the case was to go to court. If the car was to touch you then we send it to a different department who will investigate as that is not a traffic offence. If you was threatened with a knife then again we send it to another department as we report this as a crime.

So, couple of questions. Is there any point in pursuing this particular matter, as the guy is clearly dangerous and will likely end of seriously injuring someone?

And in future, short of videoing every ride, which isn't practical, is there anything else I could do when this inevitably happens again? In hindsight, I maybe could have got my friend to be a 'witness', but he's hardly independent.
