... on the motorway. There were some illuminated signs saying "50". Normally these signs are used for fog, accidents or roadworks, but they are usually left on long after they might have been useful, so most drivers ignore them. Anyway, after passing the third one of these, I noticed a high visibility jacket on the hard shoulder. Its wearer was holding something up, looking at the traffic. My immediate thought was a radar speed meter, but I subsequently realised it was a video camera. He was concentrating on the road, I was concentrating on him.
When I finally looked in front again, I saw a piece of what I took to be a vehicle loading ramp lying right in the middle of my lane. It was perhaps four or five feet long, eight inches wide, and was of a channel section, perhaps two or three inches deep.
Luckily for me it was end on, I was able to avoid it with a mere twitch of the bars, missing it by a few inches. Had the man videoing this not been there, I'd have seen it well in advance. Another lesson or two learnt.
