Right, so, insurance is not a wealth transfer mechanism. It's a risk-pooling mechanism.
We know that driving a car is risky and we could crash, and it could cost us lots of money, but on average the risk is acceptable. Instead of casting our financial fortunes to the fates like that, we pay the average risk (actuaries ho) and a few percent to make it worth the insurers' time, and we have restructured our risk exposure: we are guaranteed a certain financial impact, but it's limited, instead of being unlimited.
BUT IF YOU'RE A CRAZY MANIAC driving your new BMW down the freeway at 120mph as a matter of routine and racking up speeding tickets left and right, you end up paying more, because your behavior is risky. If you're a super-safe driver with a cheap car, you end up paying less; you don't subsidize the maniac's premiums -- not insofar as the insurance company can help it, anyway.
Contrast with Obamacare, where young healthy people end up paying more, in order to subsidize the elderly and others at risk of health conditions. That's the wealth transfer. You can also recognize it because without governmental regulation to that effect, it wouldn't be happening.
