Not comparable. In each of those scenarios, it is much, much easier to obtain insurance commensurate with the liability exposure.
I’d agree that, from my perspective (and it’s only that) people typically worry about aviation liability risks more than they should, and indeed humans are bad at calculating risks generally (the reason Las Vegas exists…). For example, if you have assets, operate a car, and don’t carry max liability plus an umbrella policy, flying YEs is likely not your biggest exposure.
But the aviation liability problem in the US is undeniably real. The aviation liability policies available to most of us offer relatively low limits AND for some reason, people are worth a lot more when they die in airplanes vs. boats, cars, golf carts, etc. Anyone with assets will need to assess how it affects them and how best to grapple with it given their individual circumstances, values, and jurisdiction. Inapposite comparisons and bizarrely wrong legal theories, both of which are rampant on the interwebs, won’t make it go away.
