As Tesla gets more information from Roadster and Model S logs, I'd really like to see an interactive battery management/ reminders section on the 17" display. I know that Tesla wants a lot of this to be invisible to owners (If in doubt, plug-in and forget) but it would be good for any battery optimisation freaks out there to have the option to call up explanations on what the car is doing and tips for better battery care.
That's a great idea. Something like "We've noticed your charing is normally finished at 2AM but you don't leave home each morning until 8AM. Would you like us to set your charge each day to be completed by 8AM?"
