It's a given the more vertical the rear of the car, the worse it sucks in crud, but the Bolt is the worst ever. Today, in a slushy winter, the front and sides were sparkling clean and the rear window was opaque.
Anyone ever had a worse rear window than the Bolt?

It's among the worst we've ever owned.
Isn't that true of just about any car? I've always noticed that with all of mine. The issue has always been, if you have a light rain or you are driving on damp roads, there's enough wind on the front and sides to push the water droplets off, yet they collect/sit on the back and make dirty water spots.

It's not water droplets that are the main concern for me. I live at the end of a 1 mile long dirt road. In dry conditions, after a few hundred yards at 30 mph or so it's coated with dust thick enough to darken the rear window. The wiper knocks the dry dust off fairly easily, but once you've used the washer, the dampness turns the next layer of dust into mud. Once you use the washer in dry conditions, you have to keep using it every few hundred yards, or just live with the fact that you can't see out your rear view window. I generally try to wait until I am out on the main, paved road to use the washer. (However, since a lot of roads in our area are dirt, it's an ongoing problem to maintain awareness of traffic behind you.)
When the road is wet or covered in snow/ice, that back window is just constantly coated.
I've got a Premier with the rear view mirror camera. Never had a need for the rear wiper or window for that matter.
Live off a dirt road so I
blow off the back of the car with a blower every time I get home. This prevents from getting mud in the hatch recesses if it rains while having tons of dust on the rear of the car.
I think that's the OP's point: On no other car that I've ever owned have I needed to clean off the rear view window after every trip. Same thing with the backup camera: Almost every time I drive, if I don't remember to wipe it off before getting in the car, I can pretty much forget about using it. Even if I do remember, I often find I can't use it to parallel park at the end of even a short trip. It's something I've come to expect from living in the boondocks, but on none of the 7 cars we have owned in our time here has it been as much of a problem as the Bolt.
We love our Bolt, but it's definitely not a dirt road-friendly vehicle, and it would certainly use some tweaks to keep road salt and slush from hindering vision in the winter. (Our automatic high beam sensor and the left rear view mirror vehicle proximity sensor also have a lot of issue with the dirt/slush.)
