The people that you can thank for the rising rates are the people driving up the cost of claims. It's not so much that more accidents are occurring than they have in the past, but rather that people are being awarded much larger settlements. As settlements increase, then premiums must also increase.
Many times the insurance industry makes it look like it's really easy to milk the system in court and get nice payout ..... when you say people drive up the cost, you should rather say ...medical providers, judges, lawyers ..... people on their own should not be able to easily milk the system. In that sense, to me, the insurance industry has messed up big time, because if it was really true that raising rates is not your primary interest, you as an industry would collectively do something about it, as any lobying group who protects their business motto etc. (you collectively do have enough power, don't say you do not ...)
