With the upcoming Tesla 2020.32 software update, there is one interesting improvement for the Model S and X - Suspension Improvements.
From the release note:
We have simplified the Tesla suspension control logic to better support both temporary and more permanent heights. If Ride Height manually adjusted to High or Very High, your car now automatically lowers after you drive a short distance. For snowy or off-rad conditions, tap "Keep" next to the Ride Height-slider to keep the height at High or Very High until you reach the maximum allowed speed. For steep driveways or places where you repeatedly need a higher ride height, tap "Always Auto-Raise at this Location." This feature will raise suspension to the saved height when re-entering the location.
From the pictures provided exclusively by our reader, the new Suspension Improvements update shows specific heights in inches.
