Deliberate mistake: After Reese rams the Terminator with the pick-up truck, the truck starts to back up out of the motel. The Terminator gets up and runs after it. Just before the shot changes, you can see that the truck still hasn't left yet. But when we cut to the Terminator getting on his motorcycle, the truck has disappeared. Considering that Sarah and Reese are in a huge pick-up truck, it is highly unlikely that they could have traveled that far in a short period of time.
