Not a problem in RWD applications.
The whole pitch was based on replacing CV joints on front wheel drive vehicles.
From the presentation it looks limiting and to be honest it looks a bit overly complicated and likely to have some massive early growing pains. CV joints are comparatively simple and this is supposed to be more reliable? That's not how it works.
There's still CV-joints there in the video despite the uniwheel. You can't turn the wheels without one. I'm probably just not understanding this but seems like instead of making the drivetrain more simple this just adds more moving parts that's going to need oil changes and replacing.
Always need a flexible joint such as CV or Universals to compensate for suspension movement. And they work in pairs, because +angular change is compensated by - angular change of opposite end of shaft.
