I wonder if the Mog driver actually saw the pug. Whilst no excuse, some years ago I had an accident entering a round about. Despite seeing a car to my left entering the round about indicating right & two cars side by side to my right ( duel carriage way)stationary awaiting the right turning car. I still got hit and to this day have no idea where the car came from that hit me as I pulled across from stationary ,to go around the round about, to turn right. My fault & made a bit of a mess of the MGBGT.
I have put it down to the blind spot on the retina where the optic nerve is attached, which your brain fills in with what it expects. It taught me a lesson in doing a double take at all junctions.
