I heard someone explaining this idea earlier this year. He was talking about how winning requires focus, and while that focus gives you the drive to go forward, it also gives you tunnel vision as you only look towards your goal. If, instead, you think about 'not losing', then the tunnel vision becomes wide open, and all the possibilities, both good and bad, become visible. In effect, it doesn't matter if the other person thinks they've won, as long as you don't lose. Driving home, I could see how this attitude would greatly improve road safety, if nothing else.
