You know, his name is awfully familiar. I feel like I've had encounters with him before back in GT5 but I just went and checked a few old videos and couldn't find his name. He must have joined a lobby at some point since I did a ton of shuffle racing. Man do I miss it. So he was the one driving backwards. I saw the car fly by me, but by the time I checked everyone was facing forward. That incident you described sounds like what is in the video I posted above. Check it out.
