Yup, without question. It's not so much about junctions or being cut up, but driving something proper quick tends to get people out of the way on motorways more. I NEVER tailgate people, never have and never will but I do close on cars quickly then leave a gap and that does tend to get most people to move over. It's not agressive or intimidating more of a "jesus where did that come from" and tends to work well. You can tell the difference as people will indicate into the middle lane rather than simply pulling back in. You will of course always get the mirror avoiders and pig heads but such is life.
Not as bad as the annoying *** ***** ****donkey****** in front of me in a new A3 this evening. Sitting in the outside lane at 60 with nothing on the inside, I came up behind them and they planted it and shot off at 90+.... then slowed down again, they then repeated this over and over again
