I imagine with free brick replacement, people would more easily and frequently forget to keep the battery charged.It wouldn't really be free; the car would be out of service for some time. And Tesla could charge some kind of nominal-but-not-insignificant service fee. I doubt that the bricking rate would be sensitive to the actual dollar cost: as Tesla points out, it isn't that easy to do. Just being careless isn't sufficient, there would have to be other circumstances like a long trip away from the car where the cost of repair wouldn't have any impact.
