Suddenly there is a car doing a pirouette in the outside lane ahead of me, I don't see what caused it but he's turning slowly around while still moving, overtaking. His front offside headlight clips the central reservation pushing the back of the car into the side of the MPV he was overtaking. I'm on the brake, trying to work out where the debris is going to go.
"Don't stop! Don't stop!" I look in the mirror and see what she means - theres a lorry getting alarmingly bigger - so I swerve through the flying pieces and step as heavy as I can on the gas.
"Do we need to stop?" I ask.
"No, theres nothing we can do or say that will help, we're better off out of the way"
