Traxler allows Sarah to take a nap on the couch, and he tells Sarah her mother should arrive from Big Bear in about an hour. Shortly after, the Terminator arrives, and Sarah and Reese flee, all of this happening at night. Later, the car Sarah and Reese take runs out of gas, and they spend the night under a bridge. A short time later, it's light out, or the next day, and they make their way to the Tiki Motel. Sarah then gets on the phone, and we find out the Terminator is there, and has killed her mother, mimicking her to get Sarah to reveal her location. The question is, why would Sarah's mother still be at the cabin in Big Bear when she was supposedly on her way to pick up Sarah at the police station? No mention is made of her stopping along the way at a pay phone to call her, and there were no cell phones in 1984. It also takes a lot longer than an hour to get to get to Los Angeles from Big Bear. The Central Division of the LAPD is about 120 miles (190Km) from Big Bear, with the first 40 miles (65Km) which is on highway 38, a twisty two lane mountain road. It's closer to a 3 hour drive in all.
