I wonder to ask questions and talk about it after I watched video of BMW i3 and real cost of charging the car in your garage, can Tesla do something like that? You plug in your electric car in your garage and after months driving and getting juice for your car your electric bill will go up. BMW installed electric meter to get very true reading what you consume, and you can easy workout how much you paid for your electric car. That will be great if tesla including something when you charge at home and connect to your tesla car app will add numbers x cost of you electric rates giving you True cost of charging your car and when you charge in super charger will show you what you save, Months or year later you will see exactly your usage, cost and savings. What you think?
