Trivia: When Conner takes out the bike between the two cars, the music being played is the same from T2 when they were in the arcade at the shopping mall.
Suggested correction: The song is You Could be Mine by Guns 'n Roses. The song does not play while John is in the arcade, Tim is playing the song on a boombox while he and John are riding to the mall. The song also plays over the end credits of Terminator 2.
Factual error: The FN SCAR-L used by Barnes would not have existed because it was only in early development when Judgement Day took place in 2004 and as such would never have made it into production.
Suggested correction: The FN SCAR-L was already being produced by the time Judgment Day took place. And even if it wasn't, it's possible in the 14 years after Judgment Day, the resistance (or other survivors) was able to continue its production. Also, keep in mind that the 2004 in this timeline was a bit more advanced than the 2004 of our world (where early prototypes of hunter killers and other machines from the future were already being assembled). Because of this, the weapon could have been produced earlier.
