If you are referring to me,..
I live in Canada and throttles are legal here, but technically the motor isn't supposed to be active unless you are pedaling.
That is an old rule though, and I don't think it's enforced?
I've seen e-motorcycles on the road with no plates or pedals, and the cops didn't seem to bother them.
They were going Well over tge speed limit too, but maybe they just didn't get caught?
I've passed cops many times and they had no problem with me not pedaling.
But the second I go over 32 kph I'm risking $5,000 in fines for riding an unlicensed, uninsured motorized vehicle.
My new e-bike will go 43 kph on a fully charged battery but I set the maximum speed to 32 to keep it legal.
I attract enough attention riding around with no hands, so I don't want to be breaking the speed limit.
I know of people that have been fined for careless driving when they were caught riding with no hands on their motorcycle, but I'm technically riding a bicycle, and I don't think that it's illegal on a bicycle?
I always grab the handlebars when a car approaches because I want to be ready for braking and steering, and I don't want to freak out or piss off anyone about to pass me.
They either give me Way more room than I need, or give me two inches of clearance depending on how they feel about me.
I always wait to grab the bars until they get close so they don't think that I'm trying to hide anything but I'm being careful enough to pass with my hands on the bars.
I did pass a cop once on a gravel road, and I know he saw me riding with no hands. (I didn't know it was a cop until he got closer.)
He just drove past me and we didn't look at each other.
I turned left in front of a road grader that was waiting at a stop sign. He had just graded the road and my tires sank into the fresh gravel more than an inch.
I rode around the corner at about 18 kph inches mushy gravel no-hands

.
I don't know what his reaction was because you can't take your eyes off the road when when you're riding no-hands on loose gravel around a corner.
