For those who advocate knocking off a wing mirror

You can get portable battery powered grinders. Not as powerful as mains ones though. No idea why you would have one in your hand whilst riding a motorbike though!

Video answered your question very well I think

OTOH, don't do it. I recall at least one cyclist who knocked the wing mirror off getting charged with criminal damage and getting convicted for it.

I just had a thought - if you broke a wing mirror and rode off, would that be leaving the scene of an accident? Does the law view the rider of a two wheeler as part of the vehicle?
