Germany's Volkswagen for example has its own insurance and banking arm. The bank got established in 1949, however I couldn't find out when they expanded in insurance.
Kinda makes sense - selling cars is a cut-throat business with ever tighter margins, the real money is to be made in financing/leasing, insurance and aftersales services.
Maybe I would know differently if I'd ever bought a car new off the lot, but I'm still driving the one I bought in 2019 and back then it still made sense to look at buying new as mostly a waste of money.
I've never looked into how truthful it is, but it smacks of idiotic/arrogant executive tropes so well I almost don't want to discover it's false
Looking over GMAC's history via Wikipedia, I find they did underwrite insurance for a time and that no other US insurance company originated within an automaker. That suggests to me Tesla's operating model here is indeed about as unusual in context as I originally - well, intuited, I suppose. I think that's interesting.
No other auto maker before them (to my knowledge) has built their own grid of gas stations, no auto maker went to the efforts that Tesla did to vertically integrate, no auto maker completely ignored the "classic" model of independent dealerships to sell and service their cars... it makes sense that they're about the first ones (at least in America) to change how the financial side works as well.
Lots of people have been "innovating finance" lately, too, not just Tesla. How has that been working out? I hear it's going great...But we were really talking about insurance in any case, the financialization of which has also I believe gone quite poorly well within living memory. Are you of age to recall the name "AIG?" 'I thought not...it's not a story the Sith would tell you.'
