What's The Best Way To Become A Better Citizen Of The Road?

We're all on the road together. Yelling and screaming at each other isn't going to help anyone. How can we all get along better on the road?

My number one thing on the road is the thank you wave. If I let you in during heavy traffic, I expect a little wave to let me know that "hey, I know what you did there, and I appreciate it." Good manners still have a place in this texting while driving society, and it feels good to be thanked for doing something nice.

Plus, if I don't get that thank you wave, I'm just sitting in my car, mad that I let you into my lane since you don't seem to appreciate it.

But what do you say? What's the best way to become a better citizen of the road?
