I was going to reply with various solutions based on my incorrect recollection of that video. After rewatching, I now have no idea how it was done.
At first I was thinking multipass from angles stiched together, but then all the cars etc wouldn't match.
I was also thinking one pass, 6 cameras on each side, stitched, but then I noticed he actually looks in every direction. If anything he doesn't look completely vertical, so the camera could be on a hover drone
Yes but how can he move around in essentially a full sphere and we don't see anything of the vehicle? Not even wheels/wheel(unicycle?

) on the ground that I could see.
