quote: But when charging a car, the cost is directly linked to how much you use it. The Tesla's EPA estimated annual operating cost is $540/yr (at 15k miles and $0.12/kWh). So if you figure the average Tesla owner keeps the car for 10 years, that's $5400 in electricity costs. You don't get that for free - Tesla simply adds it to the price of the car (so it's not really "free recharges" - you're still paying for it, just to Tesla instead of the electric company).
