It actually works that way because at the core it's the same issue: the insurance wants to reduce claim costs by enforcing/incentiving behaviour which prevents the claim to happen at all or reduce its magnitude. The difference is in the way it's done: you might get a discount on the premium e.g. if you do extra checks or maintenance or keep a low mileage, or get your claim paid only if you have proof that you did the due maintenance correctly.
Car insurance is less expensive simply because the insured risks are much cheaper than in health insurance.
