Just another thought about throttles...
It does not seem particularly challenging, to me to come up with a solution to the problems people are trying to solve with throttles without it being a throttle. There are a lot of intelligent and mechanically inclined people on this board and out in the real world who could solve this problem if they wanted to.
I'll give one example that I came up with in about five minutes. If you'd spend more time and effort you'd likely come up with a much better solution.
One nice feature of cadence-only assist bikes is that you can ghost pedal, where with just a very slow motion of the cranks and no torque you can engage the motor and move along nicely for very little effort. So imagine that you had a big red button on your handlebars that, when pressed, would disengage torque sensing (only using cadence sensing) and provide 100 percent motor power for 5 seconds. You'd want a safety cap on that button so it couldn't be accidentally engaged when you are walking the bike or otherwise not riding it. That would not be a throttle but would give you, I think, 99 percent of what a throttle buys you without being a throttle.
As an additional refinement pressing that hypothetical button for 3 seconds would disable torque sensing (only using cadence sensing) until you tap the button again. So you could ghost pedal indefinitely.
I am sure a bunch of people on here are going to post on why that wouldn't work. And they'd probably be right. But I am sure that there is a solution and it would be a more constructive use of everyone's time to get cracking and solve this problem rather than bellyaching about it. From my standpoint this wouldn't be that hard to invent, it wouldn't be that hard to patent, and you might make a nice little bit of money licensing it to e-bike makers.
A stealthy throttle would indeed be possible and not particularly expensive to implement.
During a trip to Cape Cod last fall, I stopped in a LBS who rents e-bikes on the cape. The bikes they rent are class 2 Pedego Interceptors which, according to Massachusetts law, are illegal on the cape trails. The store salesperson told me that enforcement is almost non existent and they have had no trouble at all. He said he has heard of only one incident where a park cop spotted a split grip twist throttle on a bike in a parking lot.
None of their rental bikes have class stickers and if problems begin to occur, they will make changes. They plan to remove the easily identifiable right side split grip twist throttles with thumb throttles mounted on the left handlebar. He showed me the product they plan to use and it indeed is quite stealthy, especially mounted on the left:

While I'm not a fan of breaking the law, particularly when deceit is involved, we each do what we have to do. I ride a class 2 bike and use the throttle only to get started, particularly on hills or road crossings. My torque sensor has a slight delay which means I have to exert considerable pedal force to get going and my aging joints aren't up to the task. Once in motion, the PAS or ghost pedaling in cadence mode works fine and the throttle isn't necessary.
I can understand the anti throttle class 1 crowd fearing that throttles will fuel stricter e-bike laws due to uninformed regulators. Unfortunately, a throttle is a necessity for me and until senior / handicapped exclusions are passed, I'm forced to either give up my beloved sport or ride my class 2 bike in some locations as an "outlaw".
