This is more of a pet-peeve, but my fiance has little-to-no situational awareness while driving. On a three-lane highway, she'll tailgate people in the middle and right lanes, rather than getting over into the completely-open left lane to pass them and go however fast she wants.
She also always picks the least optimal route when navigating traffic on the highway, which drives me crazy. I like to spot ahead and move in-and-out of lanes around the slow-movers and to account for the drivers around me that are struggling, whereas she will pick the most crowded and backed-up lanes to get home... and then gets mad at everyone for being bad drivers.
That's really about my only complaint to this point, aside from the "THIS SMALL SPIDER WILL KILL ME, PLZ HELP," and it's been 7 years.
On the flip side, I would love to see her list about the stupid sh*t I've done from her POV haha.
