Two Cars Playing Seesaw on an Elevated Platform

I couldn’t confirm where this video is from, but one of the Facebook comments says it’s Taiwan.  It’s a video of two cars on a giant seesaw contraption. One car backs it’s way up and onto the platform, and the other car follows so they end up nose-to-nose. And just like kids playing seesaw, the platform dips to one side or the other as a car creeps forward or backwards.  It looks REALLY dangerous, but when they’re done, the passengers wave to the people below as if they just finished a carnival ride. How they came up with this is a mystery to me.
