Tried to watch it closely, but couldn't figure out how they had it rigged to release the 2nd person once the 1st drops off. Impressive!

I'm not 100%, but it looks to me like both handles are connected by a rope along the arms with some kind of stopper, so when one side releases, the other side gets enough slack to jerk the winner loose.

The yt info is:

Le projet le plus fou de l'été !
Le premier tourniquet tracté par des bœufs en plein milieu d'un lac. Les règles du jeu sont simples sur ce drôle de manège : qui tiendra le plus longtemps !?
Grâce à un système de déclenchement fait avec 2 mousquetons de largage, dès qu'une personne lâche, la corde glisse et l'autre est automatiquement larguée. Au final, la force centrifuge était telle que personne n'a réussi à tenir au delà des 30/35 km/h !

The craziest project of the summer!
The first ever roundabout (literally turnstile, means something like the rotating swings in children's playgrounds) towed by oxen in the middle of a lake. The rules are simple on this amusing ride: Who will hold on for the longest!?
Thanks to a trigger system made with 2 release carabiners, as soon as a person lets go the other is automatically released.
In the end, the centrifugal force was such that nobody managed to hold on beyond 30/35km/h (approx 20mph in U.S. measures).

Thanks, I don't speak French

I had to look up a few words, my level is not yet up to A1 in French.
