4-6 miles? you only read the first paragraph, where the author summarized previous efforts. "If the car is driven four days a week for a maximum of 50 kilometers a day, there’s no need to plug into an outlet, NEDO’s Yamazaki said." This car maintains equilibrium at 124 miles per week, so basically anyone with a commute with a 1-way distance up to 12.4 miles, or 15.5 miles if you work from home one day a week, would not need to use a charger.
