Daniel Midah recorded the video and called 911 to report the stunt. Florida Highway Patrol is investigating, WFOR reported.
Midah also uploaded to Twitter, but warning the video is NSFW.
Midah told WPLG, "All I was thinking is, this guy is going to slide off and hit me, slide off the other side or if anything, he is going to slide down and she is going to hit him, and then she is going to crash into somebody else."
The woman who was allegedly behind the wheel of the Mercedes was arrested, WPLG reported Wednesday.
Patresha Isidore was charged with crimes against a person exposing them to harm, according to WPLG.
Junior Francis told the television station he was the man on the hood of the car and that they have an on-again, off-again relationship. The pair are the parents of a 5-year-old little girl.
Francis said that they both own the car and that they both needed to use it on Sunday, but she got in the driver's seat first. He told WPLG that he hopped on the hood to keep Isidore from leaving, but she put the car in reverse and left with him to pick up their daughter.
