They aren’t for cars just yet, so you have some time to get used to the idea.
The concept here isn’t an entirely new one. In fact, it isn’t even new for Michelin, which first introduced the concept of a wheel and tire combined into one piece (they have trademarked the name “Tweel”, seriously) back in 2005. But it is only now that a dedicated factory for these bizarre things is being built, in Piedmont, South Carolina. They will initially be used on skid-steer loaders and some John Deere lawnmowers.
Obviously, none of these vehicles move very fast, but it will be interesting to see if the technology can evolve into something more versatile.
