Sometimes my GPS will be like "go left up here," but left is actually straight and right is the exit. I think it's just seeing if I'm still awake.

It depends here, sometimes we genuinely do get a bunch of “continue straight to stay on xyz” for no obvious reason, and on highways with multiple off-ramps that split the existing lanes, it’s very common to get “use the middle lane to continue on xyz” so it’s not really as out of place as you might think. Our roads are just spaghetti garbage. Josh from Let’s Game It Out must have done the road planning.

And yes, navigating by signs is doable, but we are (were?) talking about navigation apps which provide excruciating detail, so thats a bit of a moot point. But where, specifically, they are marked changes, how well they are marked changes, and on many of them you can’t see signage at night until you are almost past it, and due to mostly being space-constrained retrofits, which exit you want from the roundabout isn't nearly as standardized as it should be, even to continue straight. Sometimes straight is the first exit, sometimes the third. Usually second. It’s not a super great implementation of the system, but the roads themselves aren't a whole lot better. Sometimes it is really really unclear what road you are already on, because only cross-streets are marked (as in you can’t see the signs for your road until you go through an intersection, and it might not be marked in a way you can see for several blocks if the intersections are with small quiet streets).. driving in general sucks, basically, and the maps direction to continue through the second exit is thus either welcome, or at least not a dealbreaker, for drivers here.
