Is AUTHOR wrong in the post ? POST : So I was just on my way out of a carpark pulling on to an extremely busy main road. One of those cases where it's almost bumper to bumper, so in fairness to me you cut a little slack to drivers that are stuck. A tall van was pulling in to the driveway. I figured there was no space beside him so the driver behind him would have to give way to the van, therefore allowing me time to exit left (left side of the road driving here, so I wasn't cutting over a lane to cross side)....

I was wrong. He had obviously sped up around the van trying to quickly overtake him, clearly I should have given way had I realised but it was too late and we were headed for a collision. I ended up fishtailing and speeding past him-after all I was in front of him the whole time unintentionally cutting him off. If I didn't speed up we would have crashed. A fair few seconds after it happened, the guy sped up and tailgated me and I started hyperventilating thinking he was going to road rage hardcore. (I have pretty bad anxiety and a history of panic attacks). I kept driving, and eventually the guy stopped tailgating, and later pulled in to a driveway much to my relief. Watching the dash cam footage, I saw him flashing his high beams at me after the near miss. I realise that maybe he tailgated to get a clear view of my rego. 
This was still all on a main road with nowhere to turn off for a while, and I was so paranoid he was going to road rage I hadn't thought to pull over. AITA for not pulling over? I'll be honest, I'm not sure if that's standard for a near miss or only accidents?
