That matches my intuition, which I'd express as: it's a particular disposition toward life risks that makes someone interested in cryonics, rather than signing up for cryonics which makes someone more prudent. (Just a hunch, I'm not saying I've thought this through.)

There are some activities I like which seem riskier than they are, such as treetop courses; the equipment makes them perfectly safe but I enjoy the adrenalin rush. When I travel by plane I enjoy takeoff and landing for similar reasons, and flying in general whenever there is a clear view of land. (Not everything abouf flying is enjoyable.)
