Yes I know its another issue. However this road is possibly the widest, straightest, most deserted road ever. I'd never do that speed on a 'normal' road. Not ever. I could see the road ahead was clear and so put my foot down a bit then the sun came through a break in the buildings.

And no, I didn't see a flash but I wasn't really looking in my mirror (apart from to briefly check if it was safe to stop quickly).
