To clarify in the US an e-bike just needs to stop supplying extra power at 20mph or 28mph depending on the class, you can still pedal faster. However I agree, the regulatory framework is way too complicated for just a random person.

In most US states, including California where this is being considered, if it goes 40mph it’s not even classified as a e-bike and already requires registration/plates.
