The video shows a car moving with the driver's-side door open and what appears to be at least two flat tires. A woman starts to emerge from the door and Lopez and his family initially identify her as the driver before noticing someone else behind the wheel.
The woman stands up on the edge of the doorway, holding on to the car door for balance.
An occupant of the car theorizes the woman appears "all doped out."
The woman swings one of her feet in and out of the car while hanging most of her body out of the door.
"Oh man, don't fall lady," someone in the car says.
The video ends with the woman still hanging out of the open door. It was unknown Tuesday whether police caught up with the vehicle, which had Tennessee license plates.
"So I'm on my way to the Airshow yesterday and we witness this crazy maneuver. One slip of the foot and this could have ended badly. Tennessee license plates by the way....so at least it wasn't us Floridians," Lopez wrote in his Facebook post, which his hashtagged "#saynotodrugs."
Of course, it's always possible that the woman was just a huge fan of cult 1993 comedy Surf Ninjas.
