What I noticed in that video was that 9 out of 10 riders riding the streets didn't give a hoot abut the no throttle law, they weren't even pretend pedaling...

The only person who tried to follow the law was the person trying to sell true pedal assist "legal" E-Bikes, He has a tough row to hoe... and that I suspect is the same in California too, you know, give an inch people take a mile...
