More cars that you'd think have rear drum brakes. Sure, legacy. But this entire discussion started with Tesla. Which has a much more sophisticated system. Even the entry level current generation Honda Civic LX has 4 wheel disc brakes (which, granted, aren't much different than drums). not really germane to the complexity of maintaining brake systems The poster I responded to said "fixing them". I consider that to be much different than your word "maintaining". Maintaining is much easier than fixing. Tesla probably keeps their codes secret and won't sell you any replacement electronic parts anyway. The practical result of this is IMO quite the opposite of "dead simple".
