I got knocked off a recently restored bike on a roundabout a few years back. I thought I had slipped on a diesel spill and it was only after the young woman had driven off that witnesses told me that she had actually hit me and asked why I had not taken her details. I did not realise because it was a very gentle bump and I was looking to my left and hand and indicator signalling that I was changing lanes. None the less it was enough to spin me around and down.
