I would have expected cars that have both conventional and regenerative brakes to keep track of how often the conventional brakes are being used and to automatically increase the use of the conventional brakes if they aren't being used enough to keep them in good shape.
The polestar 2 does the simpler thing of biasing towards mechanical brakes for a little while at the start of every trip. (I suspect this has the advantage of detecting brake failure in more controlled circumstances as well, but that's not specifically documented.)
Are there any that work that way?
