And I like how everyone here is pro when it comes to accidents ^^
No offence guys, but don't you come here saying you would handle it all jolly good.
Fact is, when something unepected happens you will throw the car to the side, brake or anything to avoid the object. You won't have time to look around your soroundings and take the right aproach. You'll only have time to see and react at first instincts (unless you're some sort of race driver who knows how to react in certain situations).
So what I think would have happend with me and most other people here if we got into such an situation:
We would have braked without checking if there was anyone close to our back in the mirrow, and we would have taken that hard right turn again without checking the mirrow.
So sorry for sounding like a prick, but I don't have that much faith in you guys
Beeing all great on a forum is one thing, beeing that great in any given situations - no.
