And if you want a couple of dozen people tell you what you did wrong, post the video up here.
If YOU think it is then do it.
If you're thinking about reporting it with video evidence then go & do so. In the worst case you'll be told to go away, which may be frustrating but hardly the end of the world, but if you don't do something the police can't do anything about it.
A stronger position does help stop these things but that doesn't excuse dangerous driving. You can be hugging the kerb and should fully expect not to be put in danger by a close pass.lol, looking at the video I could/should have took a stronger position I guess....
