Now don't you know that you're supposed to stand on the brake and yield to those who want to enter the freeway? What's wrong with you, driver?
I had that happen to me just over the PA/NY line heading up toward Binghamton. The guy was coming down the ramp along side of me, and I had nowhere to go because of the traffic passing me. He had to fall in behind, and when he got out and passed me, he pulled a "covert" middle finger salute. I looked down as he was passing, and he was holding his coffee cup in his right hand on the center console with only the middle finger extended.
