Visible crew/equipment: When Tom and Sonic pull over and the mini drone explodes, knocking Sonic unconscious, the camera pans away and you can see emergency vehicles blocking the road on the right of the screen, presumably closing down the road for filming. (00:59:55)

Sonic the Hedgehog (2019)
1 visible crew/equipment mistake - chronological order
Directed by: Jeff Fowler
Starring: Jim Carrey, James Marsden, Neal McDonough, Ben Schwartz, Adam Pally
Genres: Action, Adventure, Animated, Family, Fantasy, Sci-fi
Continuity mistake: During the chase scene with Robotnik's robotic vehicle, at one point an EMP device is launched which misses Tom and Sonic's pickup truck and instead latches onto a minivan in front of it. Except just a few shots prior, there was a wideshot of the road, and you can see that Tom's pickup truck and the robotic vehicle were the only cars on the road. The minivan just sort-of... appears.
Dr. Ivo Robotnik: I was spitting out formulas, when you were spitting up formulas.
Tom Wachowski: I was breastfed, actually.
Dr. Ivo Robotnik: Nice, rub that in my orphan face. (00:30:15)





Answer: Robotnik is a genius inventor and the quill is an incredible source of energy, so presumably he will use it to power whatever invention he can create that will help him escape the Mushroom Planet and return to Earth.
Thank you.
