I am not the type of person who will just start off on a rant for no reason. I don't "go off" about stuff on a regular basis. Sure, I'll discuss things, but, I don't generally feel angry or lose faith in mankind in the course of those discussions... but there are some things that the locals of Huntington, West Virginia really need to pay attention to.
Turn signals. Indicators. Blinkers.
When you are switching lanes, turning left or right, etc, you really, really need to use them. Always. Every time. It's moving your left hand maybe an inch or two in a minor action that helps others plan their next move in traffic, avoid accidents, and it could even save your life.
I know you're busy cursing your spouse out on the phone from the seat of your gigantic truck, and everyone else doesn't really need to know where you're going, but, just because you're doomed to an awful life with a toothless significant other and your kids are all carbon copies of Alfred E. Neuman, doesn't mean you can't move your hand a couple inches for the rest of us motorists. The rebel flag on the back of your truck tells me you're a fucking idiot, but it doesn't tell me anything about where you're going (on the road, that is, it tells me plenty about your future outlook... virtually screams trailer park until coronary).
I don't know. Maybe you're just incredibly stupid! This goes for over half of you that I've seen in my 10+ years of living in this town! Maybe you just need some education. I'll show you. It's not that hard.
Look:

That's what they look like. It's a little lever extending from the left side of the steering column! (The thing the steering wheel is attached to... that's the big round thing).
Now, the operation of this high tech gizmo may be difficult for you, if you're illiterate, retarded, or missing your left arm... but, since you can probably kinda read, I'll explain:
Pushing that lever UPWARDS, Huntington, tells everyone you want to go "right" (towards the side you write with, usually, not that you write). Pushing it down, means "left", right out the side window closest to you.
When?
Any time you are going to change lanes or turn. Do it half a block in advance of a turn, or about 6 seconds before you shift lanes.
I KNOW what you're thinking right now, trying to figure out times when it's okay not to signal!
Q&A:
Q: "But, but what if I'm in a turn only lane?"

A: DO IT ANYWAY. It reassures everyone that you mean to stick with the letter of the road. Also, not everyone knows you're in a turn-only lane, since that's not everyone's route to work or to their favorite bar that specializes in playing country music and causing the romantic hookups that are destined to destroy the world by 2150. These people need to where you are going, and if they are in front of your car, they almost certainly don't know which is the turn only lane, or if there even is one. USE IT.
Q: "But what if I have a green light, I have the right of way, so what does it matter?!"
A: People who want to turn right on red are watching for your signal to see if you are going to go straight or turn. If you're going to turn, chances are, they can turn, too. I know it blows your mind, but, just trust me and turn on your fucking blinker.
Conclusion:
You see, it's really not that hard, or, that much of us to ask that you flip a switch to communicate with us, since, our cars can very easily kill or disfigure you and your whole family. The thing is, some of us actually have a family or car WORTH CARING ABOUT... and I know you'd like to spoil that if you had the chance, since misery loves company, but if my car kills your kids, where are you going to get your welfare check?
