One should also be aware of the possibilty of a bike coming the other way at high speed. This happened to us on the Fosse a year or two ago. A short straight with plenty of time to pass, but with a blind right hander at the end. I nearly went but held back - it was one of those 50/50 decisions. A bike came round the bend flat out. Must have been 80 plus. I could have easily been on the white line at a similar speed and he couldn't have missed me. That's how easy it is.
