I didn't read the second page but from what I have read no one seems to have figured out the reason the vic was turning slowly.
Old man in vic is sitting at stop light wanting to turn left on green. Perfectly fine.
The old man sees a white truck/van in the left lane and a red mustang in the right lane coming towards him (from his pov). Since the old man is like everyone else in the world he is looking at the closer car since he wants to turn left. At this point there is most likely a large gap between the two cars.
So as the white van/truck gets closer he starts to inch out because from his pov the red pos mustang is far enough away that he'll make it. It's one of those situations where you could go and maybe have to screech the tires a little bit or you could just sit and be safe. And we all know what the old fart did.
But continuing on, the old man is inching out to go after the van/truck drives by. And then the fucker in the van turns right. I can't tell if he's signaling or if he's just turning with no blinker. So at this point you have the old man in the vic inching out into the intersection, some d bag in a white truck/van not using his blinker turning right and two fucktards driving down the road "racing" at least 60mph.
So what you have from all of that is the van turning completely oblivious to the whole situation, the old man shitting himself because he most likely hit his brakes when he saw the van/truck was turning instead of going through the intersection and then you have dumb and dumber driving down the street at least going 60mph.
That is all.
