Just returned from town with the family. I was driving 70 on the interstate in the right lane. All of a sudden I notice an older red base model Charger coming up behind me at well over 100mph. He swerved over to the right(barely missing me) and passed me at speed on the shoulder. Once he was past me he swerved over to the left late to pass other vehicles. It was the most insane thing I've ever seen.
