Reading the answers to this questions, I'd say "Not understanding the meaning of most people".

Do NOT stop to talk in doorways.

Elevator Etiquette: Let people exit before you enter. That way you have more room to enter. This applies to all things, not just elevators.

When driving, you should engage your turn signal before you start applying the brakes in preparation for your turn.

Since the majority of people in the world are idiots, and management tends to collect them at a higher rate than other roles, you will generally be rewarded more for how you make others feel than the amount or quality of your work. A person with a 10 in charisma and 4 int gets farther than the person with a 10 int and a 7 in charisma most of the time. Focus on learning better people skills. If you find a place where your work is recognized you should cherish it.

Also in the US the left lane is for passing the right lanes.

If you need to stop while walking on a path, inside or outside, step to the side. I can’t believe how many people just abruptly stop to look at their phone, have a conversation, point out something they find interesting… like my guy, would you do that in a car? Fucking GOOOOOO!!

Do not start or continue a phone conversation when going to the bathroom - public or private restroom but especially in public bathrooms.

Let the people out of the elevator that are trying to get out of the elevator before you attempt getting in.

Even if you have a green light at the crossrowds you shouldn't drive if you can see that you have no way of exiting the crossroads and would block others e.g. there is a traffic jam on the road you want to drive into.

(at least in Poland)

So many of these are "Don't create obstacles or bottlenecks".

Return your cart, zipper merge, wait for people to get off before you get on, don't block doorways.

Clearly, the truest unspoken rule is "Get out of the way!"

Be aware of your surroundings. This is not just a safety thing for yourself, but a courtesy thing for other people.

Don't make phone calls on speaker when in public. Not even if you hold it up to your ear.

If you're boarding a train or bus let people exit first instead of squeezing your fat ass past everyone to get a good seat

"Do unto others..."

Even those who supposedly devote their lives to such teachings don't seem to know wtf that means

Don't stop in doorways when walking through public places.

Here's a weird one:

Don't offer advice unless its something you have some experience with.

Googling someone's issues and giving them a boilerplate answer from the first thing you find isn't helpful and can actually be a hinderance more than anything.

don't hold your phone while driving

When it’s close to closing time, get out of the store. If you have items you want to buy, leave yourself enough time to check out before the store closes. If you’re bringing a full cart to the register 30 seconds before closing time, you’re an asshole.

The employees have probably been there for 7+ hours, and still have to clean, restock, etc. They don’t want to be there for one second longer than necessary. Don’t be the reason they get home even later than usual.

Push your chair in after leaving a table at a cafeteria. It blocks the path for people who are carrying trays and may not have a free hand to push it in themselves.

Put your cart back when you're done shopping.

People exiting a building or vehicle get priority over people entering. Let people out before you go cram yourself in the way.

When waiting at a red light, cars are supposed to stay out of the pedestrian crosswalk

You stand on the right side of an escalator/moving walkway. You walk on the left side.

It doesn't matter if you have multiple people or luggage, the right is for standing, the left is for walking.
