Possible. She definitely got lost on the way.
As she didn't know the way, I suspect she put in John's address in Waze to get there after she dropped him off.
No traffic at that time so Waze would have sent her the shortest route, towards Chapman Street (the other routes are at least a minute or more longer).
She was facing the direction of Chapman at 34 Fairview, as confirmed by the 3 witnesses in the Nagel vehicle. Which means there was no reason to do a three point turn at that point and had she turned around, it would have taken her even longer to get to 1 Meadows. I'm local, but Google maps can confirm.
