Actually, there is a thing there. I cannot find it now, but I once read a really good article about how the Bourne movie’s setting — almost all the business/industrial heart of major urban centers — is part of the inhumanity being painted by the movies.

Which is to say, it’s areas of town that often are low in children (though not as low as the movie shots, I think) that are full of people who may not (probably do not) live there coming and going from other places. In that sort of situation a time-table magic-user like Jason can come and go unnoticed, an alien in an alienated society.

Like, it’d be a lot harder to just fit in and magically and be able to ditch cops with split second entrances to subways if there was a group of kids on a field trip making the train late, or a group of parents who might immediately notice the presence of a stranger in a human — rather than technological — way. Then Bourne might have to interact with people, and not just with representations of a system.
