Year ago, I was a bit late for work. To get on the motorway you went left at one roundabout, changed lanes as you went under the motorway and right at the next to join. No lights, but there are lights there now.
There was a lad in a fast car chivvying me to go faster, and as I was heading towards the 2nd roundabout there was a space in the left hand lane, so I pulled in and let him zoom past. At the next roundabout a red car was coming to a stop in the right hand lane, as , unusually for that time of the morning a car was coming off the motorway at that junction to go round the roundabout and turn right. Of course lad in fast car simply did not read the road and went slamming into the back of red car.
I stopped to check both guys were OK which they were, but as I was already late for work, I handed both blokes my card and said 'Saw it all, happy to be a witness.'
Later that day red car man rang and thanked me for stopping and I gave him all my details for his insurance, and told him he had absolutely nothing to worry about it was all kid in a fast car's fault and if it hadn't been him it would have been me, I'd had a near miss.
Later kid in the fast car rang me and said 'I'm hoping you can be my witness. Did you see anything I didn't?'
'Yes, I said, I saw something you didn't. I saw you driving like an idiot so close to my bumper at roundabout 1, that I knew there'd be a problem if I had to brake, which was why I pulled in to let you pass only for you to slam into the back of Red Car, who was stopped there because of Blue Car , which I could see but you clearly were not looking, going right round the roundabout. So I saw 2 thing you didn't'
'Two things?' he said
'Yes, you driving like an idiot, and you not looking ahead and reading the road, that is what caused that accident'
(long pause...)
'Of course I am more than happy to be a witness for your insurance...' - funny enough he wasn't so keen on that.
