The thing with riding that on a bike path was that I had no concerns slowing down amongst pedestrians or on blind corners as it was no effort to get back up to speed. I was less inclined on my road bike due to the effort. Road bikes can get up to that speed, had a few that came close to pacing me. I understand the sentiment but I had zero incidents in four years of commuting. I was courteous, used a bell. Half my ride was up hill on the path and it did 30km/hr there. Everyone went pretty fast down of course.
I'll admit, I did enjoy passing spandex on expensive bikes with my beater bike wearing jeans. This was a decade ago when ebikes were not at all a thing.
Many bike paths seem to discourage slowing down for junctions by putting them in dips - the opposite of how some train stations are on a hump as "gravitational regenerative braking".
