Do you assume everyone around you is fully aware of what’s happening when they are controlling their death machines?

Yes. Habit.

I follow road guidelines. That is to say, if I'm turning off the road/lane I'm on, yes I indicate. The lane can be identified by lane border lines. The road's junctions can be identified by gaps in said lane border lines, either bordering another road or becoming a dotted line. If you cross the line you indicate in all circumstances. Note, though, that I was taught in England, notorious for having the most in-depth and hardest to pass driving tests in the world.

Sure. It's not hurting anyone, and especially on a roundabout it can be very helpful to other drivers.

Yeah, there can be pedestrians and bikes where I live. With these new e-scooters and ebikes, they can appear pretty fast snd silently, and aren’t always in full control of their ride when going fast and don’t always obey the traffic rules. I don’t want to confuse them.

Yes, and for a much simpler reason than everyone here: It's the law!

Unless I think having the signal on would confuse other drivers, yes.

Using a signal in some multilane turn only lanes would make it unclear if I was merging into the next lane or using the current lane to turn, so I don't use it too early if it seems like it would be confusing. I do turn it on close to the intersection to indicate that I know that it is a turn lane.

I also don't use it for exit only lanes if there is a long lane to get there. If it is short like a turn lane then I do to make it clear know it is an exit/turn.

yes. there is no stipulation to not use it because of a turning lane.

Yes, it's what you're taught to do anyway.

Not if I'm already in the lane. If I have to merge into the lane, I usually leave my turn signal on until it shuts off when I make the actual turn. If I'm already in the lane and it's turn-only you don't need it, on the highway anyway. If you're talking about intersections and stoplights like in the city and surrounding areas, I always use turn signals at those.

There has been some confusion about this question: https://www.thewisedrive.com/turn-signals-in-dedicated-turn-lanes/ https://www.thewisedrive.com/yes-you-have-to-use-your-turn-signal/ https://www.clickorlando.com/news/local/2023/12/26/watch-live-trooper-steve-explains-whether-you-need-to-use-turn-signals-in-turn-only-lanes/

I think the idea of a "direct course" is useful:

No person shall turn a vehicle at an intersection unless the vehicle is in proper position upon the roadway as required in RSA 265:42, or turn a vehicle to enter a private road or driveway, or otherwise turn a vehicle from a direct course or move right or left upon a roadway unless and until such movement can be made with reasonable safety. No person shall so turn any vehicle without giving an appropriate signal in the manner hereinafter provided.

I do pay extra attention to giving a signal when I intend to make a U-turn rather than a typical left turn.

If you don’t then your dashboard doesn’t know to get rid of the speed limit sign

At the end of the day there is no reason not to. Not like it takes any effort or costs anything.

That being said, I usually won't the closer I am to home/on my main commute. Why? Because I'm driving next to the same people every day. The same work truck with a giant butterfly on it and that one dumb ass looking cyber truck. Along with the other 100 other commuters the same day.

Actually I do it sometimes, but I feel like it does not make sense since there is no other way to go xd, but also when I do it it feels like automatic, my brain goes "turn>turn signal"
