My pet peeve is pretty simple - salmon riders.

On the MUP:

Dog walkers with their dog blocking access across the MUP with their leash or not on a leash at all.
Runners/joggers/walkers with headphones on.
Wrong way runners/joggers/walkers.
Runners/joggers/walkers engrossed in their phone and not paying attention.

In the bike lane:

Parked cars/delivery trucks.
Salmon riders/runners/joggers/walkers/skateboarders.

On the road:

Getting passed in my lane on the right by mopeds.
Getting buzzed by mopeds/motorcycles in the lane I am riding in.
Getting buzzed by cars even when I am taking the full lane.
Getting right hooked in the bike lane by a car that just passed me. I know you saw me, you passed me.
MGIFers. Must. Get. In. Front. Doesn't matter if that stop sign is 20 feet ahead of us, the driver must get in front of me.

Sharing frustration with y'all on the drivers who won't go before you at stop sign intersections. My new tactic is to just start waving them across rapidly as I approach my stop.

Those darned drivers who forget to wave me through...

It used to irritate me that during downtown rush hour, pedestrians in business attire at intersections check for speeding cars and if they don't sense them, wade across the street like lemmings, half of them with with their heads buried in their smartphones; whether they have the right of way is irrelevant.

I enjoy it more now that I see these jaywalkers as a form of blood-sport.

Shoalers are far from the worst thing in my commute (that position would be held by the assassins in their 2500# vans and pickup trucks with their 2 foot side-mirror projections), but they arouse my ire. I had not actually encountered the term "shoaling" before this thread and was surprised that most on-line bicycle glossaries do not include it at all. Various urban cycling blogs do describe the phenomenon in meticulous detail: Bike Snob NYC: The Indignity of Commuting by Bicycle: Shoals of Idiocy

On the other hand, "salmoning" is widely identified in urban cycling glossaries.

I can't imagine that is much of a problem. I mean, I KNOW Donald Trump used to sponsor the Tour De Trump, but I've never heard of him actually riding a bicycle.

He'd be the most salmon colored rider you'd ever encounter - followed closely by John Boehner.

Many of the issues mentioned here about vehicles with the following caveat, the vehicle has a bike rack. Shouldn't they be more considerate, but as a percentage they seem to be the worst.

Spitting, nose-blowing.

Dear God, I had a biking llama spray a huge loogie in my face on Friday. I announced passing on your left and BLAM! this SOB lets loose a huge spray to his left. I was on a mission and didn't have the time/interest to interact with this low-life, just shouted "THANKS.... THANKS A LOT". The biking llama shouted unintelligibly to my back until I was out of range for his voice.

Serious, WTF is wrong with people?!?!?

Mind you, I shoot snot-rockets and hock tons of loogies. I just have the decency to check my back before letting fly. I will typically refrain if there's anybody close enough to see, 'cause it's gross.

Hypno Toad

+1!

In the Dictionary of Bike Commuter Slang, this type of special being is referred to as a "Brutus".

It's the vibration -- you need a full suspension fatbike with 2psi in the tires

Ugghhh!

Return fire?

Shoulder check woulda worked.

I wasn't reacting quick enough and was riding too fast for his pace. Typically, I'm 'locked & loaded' with phlegm, but just too shocked to react.

While commuting, my number 1 peeve is drivers who forget to turn on their headlights when it's dark or low light conditions. This is surprisingly common around here and I can't understand how so many drivers can apparently see in the dark and not realize that their lights are off.

On the MUPs, I have a long list of peeves:
- Cyclists, walkers, runners who block the entire path when in groups.
- People who walk/cycle/run on the wrong side (left) of paths.
- Wannabes racers who ride too fast on paths, usually without signaling and passing too closely.
- Dog walkers with their pets on long leashes.
- Parents who don't pay attention to their kids on bikes, trikes, walking on paths.
- Cyclists who use strobe front lights when riding on paths. Why? Why? Why?

The plan is to put Schwalbe Big Apples on the suspended trike with a mini-keg on the rack.

This time of year is especially bad since sunrise is close to prime commuting time. "Why would anyone want to waste their lights when sun-up is less than 30 minutes away" My term for them is the Crepuscular Cretins

You should just tow a generator-powered kegerator

I've thought long and hard about this, seeing this thread grow, and decided that there is nothing that actually pisses me off on my commutes. I guess the biggest annoyance is when a driver crowds me - from behind, passing, crowding the right to prevent me from passing.

They are for the idiot drivers.

All bike tail lights should be flashing. And the meek and under lit shall not be seen. In the dark, I run a steady and blinky on the bar, steady on the helmet, 2 blinky reds on the back of the bike.
