When the car recognises your print it should set seat etc to the settings that were used last time you set positions, whilst being "logged in"
So..... You log in with fingerprint and the car remembers where things are set.... Next time you log in with fingerprint it will replicate your previous positions. If at any time you swap drivers they can log in with their own fingerprint and it will save their settings or if they haven't got a "user" fingerprint stored, make sure that you aren't still logged in when they start moving settings.
Pressing "name" button is how I check if I'm logged in...... I'm stored as Andy so when I press "name" the screen says directory Andy.
Wow, I've complicated that
