I think that's technically true just cause so many new motorcyclists just make life threatening mistakes before they're fully comfortable on it, but the real danger is that even if you get over that learning curve, no matter how good you are, you only have to share the road with one bad or even just momentarily absent-minded driver in a car to be killed or permanently disabled.
Somewhat off topic but I think "(X) abolition" is almost always a rhetorical mistake, even when the actual ideas are good. Like prison abolition for instance, I fully support it and people often understand and agree when I actually explain the concept but if you just say the words "prison abolition" people will jump to it meaning just letting all criminals go free with no other mechanisms in place to dissuade serious criminal behavior, and often leaves them predisposed against it even after you've explained it, as opposed to if you'd started with the actual nuanced policy proposal. Same thing happens with family abolition, school abolition, etc... it's just a needlessly inflammatory way to sell it, particularly to normies
