Now that I have both front and rear cameras, it is easier to see how this dangerous manoeuvre developed. Outside the Shrewsbury Sports Village is a Mini Roundabout that many straighten out, illegally, when they are too lazy to go round it properly. This car decided to overtake me on the roundabout but didn't consider, or care about, the oncoming car. Sundorne Road, Shrewsbury is in a 30mph area. It can be seen in the forward camera footage that I check behind as I approached the roundabout and I think it is clear from my approach and entry that I am going 'straight on' along Sundorne Road.When the car collided with me I had to fend it off to keep my balance. As it was I only just managed to avoid serious injury by staying upright from the wobbling. Police will be contacted tomorrow. Any details of the driver appreciated.
