Traffic challenge

We were headed into Memphis this week, pulling the TT in the right lane on I-55 with a semi next to us in the left lane. As we approached an entrance ramp at about 60 mph, I watched an SUV coming up the ramp pacing us. She could have speeded up a tad and gotten safely in front of us. Or she could have slowed down a tad and gotten safely behind us. But no. She continued to match our pace until we both arrived at the entrance ramp at the same time. She wound up driving in the entrance ramp right next to our pickup, looked over at us, and started honking. What the ..... ? :?

I guess we were supposed to get out of her way somehow, but running over the semi didn't seem a good option.
