The car will alway default to comfort/ efficient when u first start the car, so there may not be a need to set up a button for her (my wife prefers that setup best).
I then have M1 set up has a happy medium the way I like to drive most of the time (S2, spor throttle, sport suspension, and comfort steering...although I occasionally select sport steering). My M2 is more attack mode (S3, sport plus throttle and suspension, with sport steering). Too me sport plus steering is a little too heavy for around town /parking lot driving, but great for long highway cruises. It's one of the great things about this car, u can tailor it to your mood du jour!
