Bizarre: Three cars suddenly lifted by mysterious force (Video)

Recently, a security camera captured a bizarre road accident in China. What gone wrong with three vehicles rear lifted up into air?

Is it a cable/wire which has fallen across the road but still attached to a pole on upper left and the truck on right has caught it, causing tension and lifting the cars up before the cable/wire snaps?

Maybe, but I'm trying to understand how the guy on the motorcycle far left doesn't get pulled down and the cars/truck on the right (all but the three cars) didn’t hit the supposed cable/wire too.

If the strange event would have been caused by a cable/wire, then why I can't see the cable/wire in the video… but it lifts 3 cars!

The cause is still under investigation.
