Better analogy would be reducing your MPGs (fuel efficiency) to show a more precise clock, and arguably we all make that sacrifice to get CarPlay. Energy isn’t

Better analogy would be reducing your MPGs (fuel efficiency) to show a more precise clock, and arguably we all make that sacrifice to get CarPlay. Energy isn’t free. Even if they wrote more performant code, it would just mean less relative loss of energy to show seconds but still loss compared to not showing seconds.
