I'm not sure where you get
I'm not sure where you get the range reduction percentage. Would you share? I've seen lithium-ion batteries tested by SCE with over 200,000 without noticeable degradation. Wherever I quote a price, I make sure to say it is with or without incentives. As far as the battery pack of the Model S costing that amount, which version are you talking about? Lastly, current EV driver don't see their range drop by 20% in 5 to 5 years. It would make them unpractical.
