My only crash - I'm a safe driver, though I have scraped a couple of cars parking them - but my only real big crash was on the M11. It was a section with no street lamps, and it was really late at night so it was really dark. I was driving along in the middle lane doing 70mph, not going fast, and then suddenly in the lane in front of me there was this Ford Ka on its roof. I had no chance. I managed to avoid hitting it, but I span the car and hit the barriers. It was a write-off, but fortunately the person who'd been in the Ka was OK and I was fine, which is what matters.
