The video sparked online speculation about what sort of phenomenon could cause the cars to float in the air, but the driver of one vehicle revealed the actual cause was a fallen cable that became entangled in a street cleaner's mechanism and lifted the cars into the air.
"I was driving slowly straight ahead," CNN quoted the van driver as saying. "All of a sudden, I was lifted up. The street cleaner car snagged on the wire. The wire just so happened to be underneath our car and it sent us flying."
