Hand up, and bow head.

I have a huge purple dildo. I just start beating myself about the head and shoulders.

I think the fact that there isn't a good way I think escalates a lot of otherwise defusable road rage situations.

I usually just honk “SORRY” in Morse code.

Flash the hazards twice, also works as a thank you for letting me merge in or whatever, it’s pretty common in the UK.

I have gone to using a single hazard flash when people are in front of me as well instead of flashing high beams(reserved as the head tap equivalent for cars) because I hate when people blind me at night trying to thank me… high beams are way brighter than they used to be.

(Edit: real answer) For most acknowledgements, I double-tap a light — beams, brakes, or hazards depending on current lighting conditions and relative position of other driver — because most things I would say to them are two beats long:

• “Thank you”
• ”Sorry”
• “My bad”
• ”Go on”
• ”Nice drift”
• ”You drunk?”

Just hit their car slightly with yours. You know, a love tap, to show them love and appreciation. Then show them your extended middle finger, signifying that you are standing with them in solidarity of thinking you’ve made a mistake. If you have a weapon with you, you can hold it up and show them to indicate that you are aware you could be perceived as a threat, but are making the effort to indicate that you aren’t.

I flash my hazards for a sec. I also use that to say thank you.

Can't go wrong with the classic 🖕. 

I pretend to shoot myself in the temple.
Then I put the gun back in the glove box.

Like this 🖕

Here in the UK, turning on your hazards for a couple of flashes means either "Thank you" or "sorry" to the car following, depending on context.

Someone let you merge in? "Thank you!*

You cut someone off? "Sorry!"

Back of the hand high and visible through the rear window, fingers and thumb slightly apart to reduce the chances of them thinking your giving them the middle finger (or two fingers in the UK).

I roll down the window and do the Sorry/ThankYou Wave. 👋

Especially if they DIDN'T honk.

raise your hand?

had a brain glitch on a roundabout, nearly forgot to break for a passing car.

Middle finger possibly brake check

Honk louder to assert dominance.

Look ashamed and maybe do a single flash of my hazards.

Brake check them

Here in Hawai'i it is likely that we will give a sheepish shaka as the driver passes. Might get a tense shaka in response. I am in no way kidding about this.

I have a 52" screen mounted to the tailgate connected to a laptop on the passenger seat with a bunch of PowerPoints queued up.

Not all of those get a lot of use. I've never used SorryNotSorry.pptx, for example

Most people follow and likely understand the manual hazard lights.

Two blinks in the tempo of "I'm sorry".

I've made mistakes before and did so, sometimes they flash one quick blink of high beams to acknowledge.

🚬😎🖕

Lean into it and just flick them off. Unless you’re in America, because there, that shit will let you killed.

If I have some free time, I’ll follow them to their destination and knock on their window before they manage to slip away, and then apologize. Many seem like they’re in a hurry, despite just arriving, so I’ll just shout out my apology as I knock on their window. Depending on how bad I felt, I might try to repeat the apology next week, seeing whether I can find them on the road or their destination at the same time

I usually wave at them as though I think they're a friend of mine just saying hello.

I don't, because being polite while driving is being unpredictable and that makes things more dangerous.

Instead I do what I want others to do which is just do a better job of paying attention and driving consistently. Making mistakes happen, just refocus and avoid making more.
