Sorry, perhaps not the best explanation... The road we were travelling on has a 40 limit. It has no give-ways etc at the point of the road I was concerned about. The road curves round to the left, and you can't actually see anybody sitting (or not, as the case may be) at the the give-way junction until you are pbutting it, due to the huge brick wall, and no path to aid vision on the left - the give-way is for folk emerging from that junction (20 limit so the signs say, checked after the test with instructor) into the 40 zone.
Basically I shouldn't have needed to stop at all, if we pretend a cyclist didn't come flying out. The road that is a 20 is also an extremely steep hill, which perhaps caused the cyclist's brakes to fail-not work decently.
I, being in the left lane, stopped as quickly as I could, and had I not I would have sent the cyclist flying for a good few metres. The person to my right did stop but skidded and somehow narrowly missed the cyclist by about half a metre.
If it would help I could draw a diagram of the road and shove it on FTP, as I am beginning to understand that my crap descriptions are perhaps helping people to think I did something incorrect :-)
The DSA would *not* give me a free resit if I arsed up my friend, especially with a senior examiner sitting in the back of the car...
