That you find a property or trait that is different between them does not make them a false equivalence. The comparison is about: a) whether they are edge cases, which they are in terms of occurrence b) risk, which are comparable on a personal level Additionally, when seat belt laws were introduced there were arguments about whether it was a moral hazard. Their requiring some effort (try strapping in a small child) and considerable danger to some (again, children, and pregnant women) was not relevant to that (ultimately wrong) argument and it's not relevant here either.
