The Circle Of Driving Again - S5-E8
Factual error: The show is set sometime in the 1980's, but as Adam drives the family around the neighborhood in his grandfather's car, there are SUV models from the mid-2000's to current passing by them.
The Circle Of Driving Again - S5-E8
Continuity mistake: After Adam crosses the railroad tracks in Grandpa's car, the next quick view through the front of the windshield to the back window of their car shows a street scene, and not the railroad crossing lights, gates, or tracks that should be there.
