Cars absolutely are more dangerous when pedestrians and cars intersect. They're also not on the sidewalk, where pedestrians usually are, while bicycles (and, in my experience, especially e-bikes) tend to be. I've never gotten hit by a car. I have gotten hit by bicyclists. I'd rather not be hit by either.

If we're all on board with punishing bicyclists (and, again, especially e-bikes), who get to act like vehicles when it suits them, from being on sidewalks and potentially endangering pedestrians, I think there's a great dialogue to have about that.
