I remember back when I used to have a travel-intensive job that I was flying into airports all over the United States and getting into unfamiliar models of cars rented on the corporate account. That was sometimes no fun at all. But all of those cars fit everyone's familiar mental model of displaying fuel remaining. The Tesla Model S, by contrast, reports miles still able to drive in a dynamic model that can rapidly get out of touch with reality. And of course it takes a good bit longer to fully recharge a Tesla, even with high-speed recharging, than to pump gasoline into any other kind of car. This will take some major getting used to for most drivers.
