I think some guy in a pickup truck just tried to kill me.

I was driving home and noticed a black truck driving erratically serpentine like behind me. Kept getting closer and closer to my rear end. I had a bad feeling and tried to get away. I was in the right lane couldn't go left because other cars were there. This guy is serpentining wildly behind me close to my rear end. I had to whip it very quickly into a taco bell lot to get away. I drove through the lot waiting to turn onto the road that intersects the road i came from and there is the truck waiting at the light. I refused to turn onto the road until he left. He drove off normally so I dont understand what that was about.
