I have had two instances recently where I have felt that I am being put in danger by the car behind me who choses to go through a red light when I have stopped.
In the first case I was aware that he didn't sound like he was stopping so I got the impression he was intending to continue through even though I was in the primary position and slowing as the lights changed from amber to red, so I moved to the side of the road to let him through - sooner have the nutter in front of me and out my way.
