In the CinemaSins video titled Everything Wrong With Terminator 2: Judgment Day, some interesting questions are given concerning how the T-800 initially tries to find John Connor in Los Angeles.
After the T-1000 arrives at John Connor's foster parents' house, Janelle Voight says: "There was a guy here this morning looking for him, too." The CinemaSins narrator says: "What!? So John was gone in the morning for whatever reason, came back to the house to work on his bike, and Schwarzenegger STILL couldn't find him? Where the hell is he looking and why didn't he just camp out around the house?"
In this related question concerning "T-800 John Connor Acquisition", it is explained that John Connor (in the future) would have given the T-800 information regarding where he was living in 1994, and "likely places he would be hanging out" in 1994.
However, the T-1000 may not have had information concerning places where John Connor would often be in 1994. Doesn't it seem unlikely that the T-1000 would somehow "randomly" or "coincidentally" find John Connor in Los Angeles? So why did the T-1000 leave the foster parents' neighborhood to look for John Connor? Wouldn't it be more likely to find John Connor by waiting at his residence instead of somehow trying to "randomly" or "coincidentally" find John Connor in Los Angeles?
