I see it as a sort of amateurization/tragedy-of-the-commons that increases the likelihood of injuries.
As a parallel example, from what I can tell, injuries on electric rental scooters haven't really dropped too much, they just stopped being news.
Surely even skilled cyclists should be permitted to use bike paths as long as they don’t tear by everyone at 40 mph. And I’m genuinely a bit unclear as to why no-pedaling-needed bikes shouldn’t be able to mingle with bikes as long as they follow the rules.
