Continuity mistake: In the scene where Bacala is telling Uncle Jun about his father and the accident, Uncle Junior gets angry and starts throwing things around, he is wearing glasses. You can see that in between throwing one of the items, he is not wearing his glasses, then he is wearing them again.
Visible crew/equipment: After Tony gets written up for speeding, it then cuts to Bryan Spatafore parking his pickup at the curb, and just as the pickup's door opens and closes, we can see the reflection of the boom mic on the vehicle's door and window.
Answer: Bobby Jr. was talking to his son (Bobby III) on the phone, not Karen. Karen couldn't get a hold of Bobby Jr, so she called her son and told him to give his dad a message. For whatever reason, Bobby III waited to call his dad (perhaps he couldn't get a hold of him at first as well). During this time, Karen had her accident and traffic backed up enough for Bobby Jr. to be stuck in it.
