I’ve seen this in some roads. There used to be a major road in my city that runs north-south. And yet, at a random intersection, GPS directions would always tell you to turn right, then left, then go a block and then come back to the main road and continue on your way. It made no sense.

I think someone finally dug in and saw that the map data our city published was missing a tiny connecting node in that intersection, so all the routing algorithms saw that as “the road ends here” and found a way to route you around it.

They fixed it after several years and newer GPS devices (and web stuff) finally routed properly.

But you’re not wrong - Google Maps IS fucking drunk.
