I think the biggest problem is the timeline.
Some have her leaving work at 4:05, another at 4:11, some at 4:15.
Some have her pulled over at 4:20 others at 4:30. She couldn't have left work at 4:15 and been pulled over at 4:20 and 4:25 would have been a huge stretch. If she left work at 4:05 or 4:11, she could have made the trip. If she left at 4:05, but didn't get pulled over until 4:30 or 4:3x, then there's likely a stop somewhere between work and the pullover.
Then we have her leaving at 4:40, text at 4:42, unseen text at 4:53
Is 4:40 an actual concrete time or could she have left at 4:42 and 4:40 was the estimated time? If she had texted someone at 4:40, but before 4:41 as she was pulling out, could the text have not been received by the receiver's phone until 4:42?
