Oh yes... a few years ago DH and I were courting I wasn't feeling great but insisted on catching my flight home (long weekend in France). On the way I asked him to stop the car. He couldn't because there was no hard shoulder and there were cars behind us.
I opened the window very quickly and hung my head out of the window. English car on the "wrong side" of the road and cars coming towards me. Backsplash in the wind may have coated the windscreen of the car behind us. 
I never made it to the airport. We found a McDonalds and Mr TwinLolly got me a spare change of clothes while I got cleaned up. I had to phone my boss and tell her of my predicament. Also i had to let the airport car park know. 2 days later we drove back to the UK and fetched my car, no extra charge, and I went back to work.
