I don't think there are many of us, but I drive 1,000 miles a week. I passed the 200,000 mileage point, so I thought I would share info on my small worn-out 60 battery. My FULL charge is 170: My 80% charge is 151: I drive fast, but my average usage is 352 Watt Hours/mile: I charge for free at my house because of Solar, using 51,727/kWh: and at my office because of Solar, using 21,465/kWh: Which means when you take out the free Supercharging I have done, I have used 73,192/kWh to drive 200,000 miles. If I did NOT have Solar, it would have cost me $5,050.25 to drive 200,000 miles (Reliant's rate is $0.069/kWh in Dallas, TX.) That is $0.025/mile. I love it! The one negative? My remaining mileage is WRONG! If I hit 31 miles left on the Dash, the car will stop. Out of juice.
