I can’t tell if people are completely oblivious, or intentionally trying to make others angry.

I have a couple examples that happen at least 3x per week in my area. I drive a RWD GMC Sierra, bone stock, smallest engine, not one of the “look at how big my rig is” trucks. Only added that in case trucks get it worse, I don’t know, I’ve only driven pickups and SUVs.

There are quite a few places with 2 or 3 way stops but 1 direction has no stop. I can have my indicator on, when it’s supposed to, and be going fast enough I’m obviously not stopping. Still at least 3x per week some little Chevy Sonic or Honda fit will throw itself in front of me. Now, I am always expecting the worst, so I haven’t ever hit them, just makes me angry that I gotta slam my brakes and hope the vehicle behind me isn’t on their phone. Maybe they thought it was an all way stop, but even so, they’re really just gonna throw themselves in front of something 2x larger and heavier… I don’t get it.

Another one is highway merging/courtesy. Road open, and I’ll move to the left lane so the person can more comfortably get on the highway. For whatever reason, people really just like to match my speed after that. I speed up slightly, they speed up, I slow down to try and just let them go, nope, they slow down too, which gets me a little frustrated and I just floor it around them. Usually followed by them tossing a finger at me. Again, I don’t get it.

I don’t drive aggressively, I’m very attentive, and very courteous. I mean I won’t stop in the middle of the road to let you out of a parking lot, but that’s not courtesy, it’s impeding traffic.
