“Most people drive all their lives and don’t have so much as a fender bender.”
Whether insurance companies charge too much for what you get is certainly a reasonable argument, but your statement above is incorrect. Statistically, an average driver has 3-4 accidents over a lifetime of typical driving. I realize that may not apply specifically to you.
Buying vehicle insurance is purchasing an intangible commodity - i.e., protection in the event of a loss - which you typically buy on an annual or semi-annual basis, and which you use up every day the policy’s in force whether or not you file a claim. It’s not intended to be, nor is it sold as, a savings plan.
As far a needing a lawyer to understand an insurance contract, I can’t recall any kind of contract where I wouldn’t have benefitted from having a lawyer to truly understand it. That’s not just insurance - that’s the law and lawyers. Some insurance companies have come out with a “plain talk” policy (although I believe they still could be made more understandable).
Do people sometimes have a legitimate beef with insurance companies? Absolutely! Do people not often not fully understand what they’re purchasing when they purchase insurance? Absolutely.
I never worked for Progressive nor was I ever interested in working for them, but I know that the rank and file of any company generally has zero input on the nature of the commercials that their employer runs.

Are these statics from the insurance carriers? And do they mention the severity of these collisions? Were they bumps in park lots, minor fender benders? You can bet the rent most of them were very minor.
Do you think someone who's had a reported fender bender in their driving life is able to recover the tens of thousands of dollars they pay insurance companies in monthly payments over a period of say, 50+ years?
Come on. It's a win win racket for the insurance man. Otherwise they wouldn't have built all these elaborate hi rise monstrosities in every city.
Btw, ya think the average person in the U.S. understands their insurance contracts and all the legalese, many of which can be dozens if not many more pages long? Come on.
So on top of paying these people all your life, the insurance companies advise that people should hire a lawyer to go over their policies?
Lemme ask ya, do you people in the insurance industry advise your clients to hire lawyers so they fully understand these contracts, so they're fully protected and fully understand these contracts?
If not, why not?
