My classic manoeuvre was whilst driving a loaded 17 seater minibus (Ford), with a trailer on the back, in convoy with two others in Belgium.
Approaching a motorway to join via the slip road, we are slowly building up to maximum speed of 57mph, when a Beemer driver, seeing the potential 5 second delay our convoy could cause him decides to cut up the inside using the hard shoulder.
The Beemer drivers second mistake was he realised too late that we are in right had drive vehicles, on the right side of the road, so no one is going to cut up the inside of us without being spotted!
The front van/trailer straddles the hard shoulder, the middle van/trailer moves along side and the rear van also straddles the hard shoulder
We then reduce speed to around 45mph
Three vans of teenage Scouts think this is hilarious as we majestically sweep onto the crowded motorway to join in the the convoy of trucks all travelling at 57mph who spot what we have caught and close ranks.
Great amusement was had by all
