At the beginning of the Azerbaijan scene, you'll see the helicopter cutting trees. Notice that its discs are dual-layered. Even if you can't see it, consider a knife cutting a CD. It just can't do it. Now attach two knives via duct tape and try to accelerate the device. The CD will fall apart in three slices, one slice for the left part, the other for the right part, the other from the middle gap. So, going back to the slip-up, if there are two discs that cut the car, where is the middle piece? Otherwise, view the footage again. The two halves are not really halves, they seem narrower than a half of the car would be.
