Revealing mistake: When the 2nd BMW SUV is blown up on the dock, you can see the underside of the vehicle which reveals how they removed the drive shaft to help reduce the weight of it in order to flip it easier. There are also 2 jets of white gas seen coming from 2 pipes under the rear bumper which are what launched the vehicle end over end.

Answer: Throughout the movie, Face has shown to be impulsive, and constantly deviating away from Hannibal's plan, in fact Face several times screws up because he hasn't followed the plan.
