Discription of Events: Heading west bound on I-94, I was in the left lane passing a car as this car was coming up on me. I signaled to get over and once i passed the car i started to get over when this car sped up and swirved around me. I caused me to swirve back and almost lose control of my car. Three other cars followed suit swerving around me. They were "decorated cars" with baby dolls attached to their cars and paint jobs to mimic movies.
