Your comments dodge the gist of my initial comment, which was that a bike or scooter being motorized does not make it inherently more dangerous on a bike path, it is all how the vehicle is operated.;

But regardless, speed itself isn’t the problem, it is speed differentials. And I have seen bike dudes jam through crowded bike path conditions at way more than 18 mph. Like, try 30+ mph.

And yes, you are right that clusters of clueless pedestrians sprawling across the width of the bike path are a real problem. I never said they weren’t.

I was drawing a distinction between motorized and non-motorized bikes, and that non-motorized ones are capable, and in my experience more likely, of causing a problem of speed differentials among users.
