Corrected entry: Throughout this show, it is apparently possible to drive between any two locations in the Los Angeles area within half an hour. It takes Jack approximately half an hour to drive from the downtown train station where he sees Khalil lead Andrew away to isolated areas that seem to be at the edge of the city (we hear it is Ventura County). Even if the streets were empty, the Los Angeles area is large enough that this would not be possible in real life.
Corrected entry: It is not clear what time during the year this particular day takes places. It is a weekday, which we know the office in which Jack secures the override device from Habib is filled with workers. However, neither Behrooz nor Debbie go to school. It cannot be summertime because the sun sets before 7PM which is not realistic. At the same time, there is a school bus in the scene where Jack is following the terrorist Khalil toward the location where Heller and Audrey are being held hostage. If its during spring or winter break the bus would not be there.
