Remember back in 2004, when we all had those self-driving, voice-activated cars that looked like this◊? That future got erased along with the time machines as the ultimate result of repeated attempts to alter the timeline. This is actually Larry Niven's Law of Time Travel: (paraphrased) "If a device capable of altering the past can be created, the past will be altered continuously until a timeline is created where that device does not exist."
Not really all that important, but, in the ending, wouldn't Max's former partner, Lyle Atwood, be walking around the station somewhere? Because if 1994 Aaron McComb was killed being fused with his 2004 self, then he wouldn't have been able to put any TEC agents on his payroll and Atwood wouldn't have been in the 1920s to help finance McComb's campaign. Of course, it's possible he may be there, we just simply don't see him. Or he may be off duty. Then again, it's also possible that, in this new timeline, he along with a few others never joined the TEC at all.
