When things just don't make sense some kind of mental issue is often the answer.
She was going to meet friends 7 minutes away. Instead, she drove right past the meet up place to an industrial area 14 minutes away. She got pulled over for an illegal lane change, which she made while stopping at an intersection. This tells me she changed her mind on which direction to go at the last second. She seems to be in the left turn lane during the traffic stop, so despite needing gas, she was apparently going to turn onto 9-Highway and continue north. Cop points her at QuikTrip and tells her to get gas. After getting gas, she pulls her insurance tracker, but doesn't disable her phone, which makes no sense times two. She then heads North, when she was supposed to meet friends to the South.
There are just so many things in there that make no sense whatsoever. She makes decision after decision that make no sense. There had to be something going on in her head.
