Near the beginning, Nora and two of the other ladies start giving a hard time to the cop getting ready to give a black car a parking ticket. The cop leaves without giving a ticket, then Nelly says that it is not her car. Her car is across the road. Later, the ladies are seen removing their shopping from the boot of Nellie's car, which is orange. Either the ladies are all seriously color blind, or the crew just didn't provide the right color cars.
When Nelly turns to drive back onto the road after doing a 3-point turn, she doesn't turn the steering wheel.
