So the interesting thing about this is the ... peddle-by-wire drivetrain? So unlike a normal e-bike, when its battery dies it turns into a stationary bike.

I love ebikes and generally like what Rivian does, but in a very competitive market it's hard to see the appeal of this.

This is an electric motorcycle with pedals. The presence of pedals that only-technically contribute to motion is a regulatory-dodge not an intended feature.

As long as it only moves if you're peddling, it passes the regulatory test.

I don't think this is true, class 2 e-bikes are allowed a thumb throttle up to 20mph

I stand corrected. I did not know that class 2 allows for throttle-only operation.

This is a Class 3, so it needs pedals to hit 28mph. It also has a throttle up to 20mph for class 2 operation.
