On the other hand, don't be the person who sits there way too long after it turns green, holding up the line. Most likely texting on a phone (usually illegal, but doing it anyway) or anything else other than actually paying attention to the road.
Also don't be the people who decide to just stop their cars in the middle of the road to have a heated conversation back and forth, literally holding up traffic on both sides of the road. Just don't do it. The road is for driving, not for having long chats, friendly or otherwise, with other motorists. Pull off the road somewhere if you want to do that.
Also don't be the people who want to street fight in the road because your road rage is too high. Maybe consider staying home and never driving.
