You're describing one particular kind of (high-end) e-bike. Many perfectly legal, unmodified e-bikes do not have torque sensors. If the bike has a cadence sensor, like mine does, then it doesn't care about how much torque you're applying to the pedals. All it cares about is how fast they're turning. And at the higher speeds (around the 20 MPH limit) the gearing and small wheel sizes on mine are such that one would need to pedal very fast to exert any significant pressure on the pedals. A much lower pedaling rate with no pressure will still maintain the top speed on level ground.

There is no significant difference between "pedal assist" and a hand-operated throttle. It would be really nice if the politicians would recognize this and remove the meaningless class 1 / class 2 distinction based purely on the location of the throttle. (Though to be fair there are many more sensible places which already treat them the same.)
