I’m always amazed at how many cars of various types I see that have tail light designs where the lens is split between the rear quarter and the trunk lid, and the two sections are badly misaligned. What makes it even worse is that the misalignment is usually asymmetrical, with one tail light well aligned and the other one way off. Can’t imagine how the factory could ship something like that.

On an unrelated note, has anyone else noticed how often you come across a car driving down the road with its back up (reverse) lights on? I see this fairly frequently and can’t figure out what would cause it and why it is so common.

Excessive use of perfume and/or aftershave!
No doubt about it!

Subaru even had a recall for this very problem.

Not meshing with theory, this problem appears most commonly on older pickups?

Unlikely they are using LEDs. With the low current draw, the contacts are no longer self-cleaning.
