Continuity: Towards the beginning when Dave leaves the record label (after he steals the muffins), downstairs you can see a girl in a pink top, a delivery guy and a black guy in beige boots. The girl in the pink top passes Dave, then it cuts and you see her in front of Dave. Then it cuts again and you see her behind Dave and going around a corner. Also, the guy in the boots does the same thing a few times. And the delivery guy comes up close to the shot in the end, then they show him again just getting close.

Continuity: In the end, when Dave is chasing Ian, we see many headlights behind him. However, once the chipmunks hop up and Dave slams his brakes, we see no lights and no cars pass him. Also, the whole time they are talking, no cars pass again. When Alvin steers the car there are all kinds of cars again flowing both directions.
