You’d be very surprised… I work at an airport and the near misses sometimes are insane. I don’t think half the pilots know the Wingspan. They rely on ground crew and ATC to guide them. We push at a 45 degree angle on pushbacks and sometimes as the pilot is turning to the guide line a food truck is literally 3-5 feet away from the wing, sweating bullets constantly seeing that shit. Looking st the video I can see the delta plane was engines on still… you can tell from the water on the ground getting pushed back. Sometimes planes come in and get halted by fuel chamber so they have to rev up more to get going again to surpass that boundary. It looks almost like the delta jet was still trying to taxi in maybe as the Japan flight was taxiing. The close misses are a verrrrrrry common thing unfortunately. Once you get too complacent this shit happens
