Several bits have been added in OTA firmware updates, these I found easily in changelogs:
-February 18, 2016 (2.12.45) Creep on/off setting linked to driver profile
-March 24, 2014 (1.51.88) Firmware 5.9 Smart Air Suspension Speed range for High and Very High has been increased.
You can now drive at Low at any speed, and you can set the speed at which the car transitions to low. Controls > Settings > Vehicle. This is saved to the driver profile. Options are Always, Never or any speed from 55 to 100 mph
-Oct, 2013 (1.45.45) Firmware 5.3 Seat heater settings added to driver profiles.
-Version 4.0 (v1.17.50) November 30th, 2012 Metric/Imperial Units
I used to own a year 2000 Jaguar van den Plas - even back then it included a feature to move the driver's seat back, and sterring wheel up out ot the way, to enable an easier vehicle exit. I was shocked to experience the Tesla S without this basic feature.
But they are not saved with the fob. I want driver profiles to be saved before I get in the car with my fob so that I can actually get in the seat after my wife who is a foot shorter than I am has driven it.
