Two days ago I had an oncoming car cross over the double yellow and join me in my lane. Had to take extreme evasive action and use up all of the road verge to effectively make an extra lane. There was only centimeters in it. I always left foot brake and cover the brake when on oncoming car is approaching. I also drift left in my lane to give me as much room as possible. All of this contributed to avoiding a very bad head on.
Also, although I find the AMG stuff on the Merc a bit of a wank, particularly in Oz with our pedestrian speed limits, I can honestly say the big rubber, brakes and suspension are good to have when you need them.
Stay safe out there folks and drive defensively.
