“Did you watch the video?.......”
No - did you see something amiss with what I wrote?
No, there’s nothing wrong.
The CVT’s in the Nissan cars you mentioned are belt driven and prone to failure from wear. That was covered in the video. You dodged a bullet.
No belts in this CVT design, just gears. But it’s just a prototype and hasn’t been proven in the real world yet. It hasn’t been put in a vehicle, tested for wear, torque stress on the gears, etc. But it looks promising, and it doesn’t seem all that complicated, at least to me...........................
