I see all of these all the time. I think it a sub conscious thing like they feel your slowing them down when they are behind you. They speed up when you try to pass because the think they have slowed down. And groups of cars I have no explanation for besides people feel safer in goups or something. But you also have people that do these thing purposely like the dicks they are.
Don’t forget the people that just have to talk over you even if your half way into a gad damn story FUCK! I’m getting pissed just thinking of these a-holes.
I can see why people don’t inch up, I mean why commit to an intersection if you might not be able to turn because there is a lot of oncoming traffic? But there are people that sit through green lights because they are completely nutless, and he’ll be there all day if he doesn’t inch up to the turn.
