Name your top three pet peeves.
I can only come up with one pet peeve, and that’s probably because I deal with this one thing almost daily.
Driving.
I’m always amazed, and irritated, by the things I see people do when driving. I am constantly on guard while on the road, and try to give proper respect to pedestrians, especially since I’m in a giant moving death machine and they’re, well, not.
People behind the wheel here have almost no spatial awareness or sense of timing, and they don’t read signs.
Right turn lane from one street becomes a new lane on another? People will stop and treat it like they’re merging into oncoming traffic, completely ignoring the new land added sign.

Left hand merge into traffic? Nope. One of two things typically happens. They never get up to speed and stop near the end of the merge lane, or the drivers in the lane they’re merging into don’t get over to allow room. First one is mostly in the city limits, the second is interstate traffic.

And on the subject of interstate traffic. Pay attention to your mirrors! If I’m behind you and I get over, maybe you should check to see WHY. It’s either something ahead (vehicle with flashing lights, construction, someone merging, slower vehicle) or you’re going too slow. This kind of ties into my motorcycle training, which I didn’t learn in Drivers Ed as a teenager. Always be looking 12 seconds ahead.
I could probably rant forever about this, but then I’d be writing a novel, and I’m already trying to do that for something else.
