Other mistake: When Belle supes up her cab, you see that the top of the cab where the number is comes down and there is a license plate that comes over the original plate so the cops can't find the cab after she speeds. Yet the original cab number can still be seen on the cab doors.
Continuity mistake: Near the end of the movie when Washburn is driving the taxi backwards to get Williams to the hospital with Lt. Robbins. Lt. Robbins is sitting in the backseat behind Washburn, and Williams in the backseat behind the passenger seat. After Washburn spins the car from driving in reverse to driving forward, Lt. Robbins is shown sitting in the backseat behind the passenger seat while talking on her cellphone. She is talking with her head turned slightly to her left, and Williams is not on her right side any longer. Williams is returned to seat behind the passenger seat after they crash into the lobby at the hospital, and Lt. Robbins and Washburn use the passenger side rear door to get Williams out.
