On the M20, inside lane, safe distance but only two lanes. Car in front suddenly lurches to the outside lane revealing a stationary car in my lane. A safe distance between me and the moving car is now as nothing bearing down on the stopped car. I had an Audi in the process of overtaking me, Just managed to avoid the stationary car and accelerated to avoid the Audi too. No hard shoulder for the stationary car to take refuge in. I guess the guy behind had to do the same as me and that no one else hit that car. When swmbo recovered her power of speech she was full of praise for me avoiding the collision which is about the first time in 44 years a positive comment has come my way.
