Continuity mistake: All shots of the Jeep Cherokee prior to it crashing (and during the process of flipping over) show that it wears factory-optional silver steel wheels of a 'star' style. But as the wreck settles upside-down, it's wearing plain steel wheels (like those found under full wheel covers or on a spare tire).
Plot hole: When John inserts Cameron's CPU, she restarts nearly instantly. She recognizes John right away and speaks to him by name. Yet seconds later, we see through her eyes as her system reports recognizing him, but she already does.
Revealing mistake: When Sarah and John leave the chapel after attempting to disable Cameron, they run across the road and almost get hit by a car. Watch Sarah's face in the close up shot: she's trying not to laugh and is somewhat smiling.
Revealing mistake: As Cameron flips over the Jeep Cherokee, the smoke coming from the bottom of it is from the cannon used to flip it, the cannon in later shots then disappears, more notably when the camera goes above the Jeep with Sarah crawling out.
Answer: It was cancelled due to declining ratings. Season Two had about half as many viewers as Season One.
