You'd have to do a test to see which memory setting it uses. My wife and I both use the saved settings in Memory 1 for each of our Profiles, so after I confirm it's me driving, my Memory 1 settings automatically start engaging, and I don’t have to touch a thing, which is why I previously made the "no buttons to push" comment. The same thing happens for my wife.
Some guessing on my part:
If you pushed the Memory 2 button on your Profile the last time you drove, I’d say there’s a good chance your seat, steering
wheel, etc. will use your Memory 2 settings the next time you get in and don't touch either button.
More guessing:
To take it a step further, if you’re the tall one in the family and saved the Memory 2 button on your wife’s Profile just to get into the car comfortably after she drove the previous day, I’m guessing her Memory 2 settings will engage the next time she gets in and doesn't touch either button. Plus, those aren’t her normal driving settings, so she’ll need to press the Memory 1 button after confirming it’s really her driving.
