I know this is really stupid, it is a PV and it doesn't have to make sense, but this thing has been bugging me ever since seeing it the first time. In the music video of "Image" our heroes save an old lady from a truck rolling her over. Since a truck doesn't just come strolling down the road by itself, do they kill the driver in the process to save the old lady? There is no way anyone could survive that impact. Superman would have handled things a bit differently and would have tried to save both.  Is it supposed to be a magic self driving truck (since they don't show a driver) or maybe there is a deeper meaning to that scene in the way that the truck is supposed to represent something in life? What are your thoughts?

This is actually a question that was asked at the ACEN Chicago Q & A panel. If I remember correctly the answer was that it was a self driving truck. Someone can correct me if I'm wrong.

Lots of fans asked about it when Image MV was broadcasted.
In the scene, it is a self driving truck so no driver in! I'm too lazy to find sources but it was also announced by scandal_band twitter that no one was injuried in the clip

Their manager Eisuke had clarified in his twitter that the scene is a stray truck.
The translation is in this forum. Maybe some what hard to find.
My guess is the driver forgot to pull the handbrake properly before leaving the truck.

In the PV,  you can clearly see that no one was in the  truck, if someone was in it, they would have shown them seeing the old lady, and trying to hit the brakes (I doubt they were trying to hit the lady on purpose lol) I noticed that the first time I've seen that part.
