Closest I've come to crashing for years was at that bit earlier on this year, and it was a private hire taxi that did the honours exactly as you describe. Thing is, I was driving an 18 ton council gritter, it was about 2.30 am, and we were the only two vehicles on the whole stretch of road. I just about had kittens trying to slow down and keep the gritter under control, while the fucker driving the taxi battered on completely oblivious to what was going on behind him.
