Continuity mistake: In this episode we learn that Barney doesn't know how to drive. But throughout the whole series there are reference that he actually does, such as: In 'Come On' (22nd episode 1st season) : Penelope says to Barney: "We had sex twice in your car." In 'Moving Day' (18th episode 2nd season) : Barney drives away with Ted's rental van. In 'The Bracket' (14th episode 3rd season) : Barney stole Holly's SUV as they were camping.
Factual error: When Ted is having a flashback about the first road trip in the Fiero, which would have happened around 1997or 1998, they are passed by a 2002 GMC Sierra. (00:06:10)
Chosen answer: In a flash forward scene in Season 8, it shows him with his first born: a daughter.
