It's not that great for a solution. You can set the 90% in other cars too. With the extra benefit of being able to use 100% when you occasionally want to.
That has to be an option, which you need to know exists, and actively use.
Hell, bmw could expose that exact same setting the other way around, and maybe they do. But defaults are important, and from a UX perspective I think they have the better one.
