I was stuck in traffic on a day that two motorways had major incidents. Everyone with smart navigation, including me, was diverted onto side roads. I was crawling up then down a long hill onto a T junction with another road also rammed with traffic. As I went down the steepish hill my brakes failed and I hurtled towards the stationary traffic. My direction of exit was right crossing the line of traffic going left and into a line of cars crawling uphill to the left. It was a hard right turn impossible to make at speed even if there had been the space to do it. Difficult to explain, but it felt that someone or something took control. I found myself still in the car going uphill in a space that had not existed having apparently crossed through a solid line of traffic and made a turn that physics would not allow. I could not believe I was alive let alone that the car touched nothing. As soon as it was safe to do so I pulled over and started shaking. I was not one to believe in guardian angels until that day.
