Problem Dog - S4-E7
Continuity mistake: Skyler makes Walt return the Challenger to the car dealership, but Walt decides to take it to a parking lot and spin donuts with it. Just before he crashes, he's spinning clockwise, starts to lose control, and tries to correct it by turning the steering wheel sharply to the left. However, from the overhead shot, the marks on the pavement indicate he was spinning counter-clockwise and tried to correct by turning right. (00:05:50)
