Here in NYC there is that same certainty. Not into oncoming traffic, but traffic moving in the same direction on a 2 or 3 lane road. These people will literally just swerve into your lane without any regard to avoid something. And then when I honk at them they give me the finger like I’m the one who is supposed to politely stop short and allow them to proceed.
What annoys me even more are people who will park half in a parking spot and half in the driving lane forcing people to have to go around them, thus creating the situation mentioned above. It takes 2 seconds to properly move your car so that you are not in the driving lane. But they cannot be bothered. Driving lane be damned; they are going to obstruct it.
I think I need to leave this place.....
