I got to the front of an accident on the A3... waited had a chat with some bikers then the police opened the road.... but couldn't zoom off as they lead the traffic for a couple of miles first
As for filtering... when someone is filtering faster behind me i try and move in when i find a safe place to do so... just diving into any gap can be dangerous and the person behond me will have to wait until i find a gap big enough to park my a*se in for them to go past.
Don't worry about the sv1000 i think no matter how quick you pulled out the way you would have got the same reaction... some people are just ****s full stop.
