I did a round trip Huntsville-to-Atlanta to pickup two light-weight rims and better tires: Travel time: 2:00 AM to 10:45 AM 30 minutes to wait and load tires Distance: 370 miles Left with 100% SOC and 232 miles estimated range Arrived with 20% SOC, 46 miles estimated range Recharged to 67%, 24 kWh, $2.64 Supercharger costs: $8.58 Biology breaks while Supercharging: 21 minutes - bathroom and coffee 22 minutes - breakfast So these metrics give: 370 miles / (8.75 - 0.5) hours = 45 mph (state roads) $0.023 / mile Supercharger costs $0.032 / mile Supercharger and home costs Leaving the loading dock, I heard the 'tick tick' and stopped right away. There was a metal screw but I removed it before it punctured the tire. Bob Wilson
