Also, that software is so non-configurable these days: Is an “Automatically accept better routes” checkbox that esoteric?! I’d say I want to find the product developer responsible but it seems like it’s most of them these days. It’s like not being able to turn off auto-playing previews in streaming apps.
Sorry, rant over.
I've had cases where I was on a highway far away from any exits and there was a jam caused by an accident, and google maps started flip flopping between 2 different "optimal" routes that required me to first take one exit that's ahead of me, and then another exit that was far behind me. Presumably google was seeing the traffic jam and determined that my current route is no longer optimal, and wanted me to do a U Turn on a highway where there are no exits.
