The Tesla S isn't an economy car, nor an inexpensive car. It's a BMW 6 Gran Coupe, M-B S, Audi A7 competitor; priced similarly, and has similar performance. The efficiency in cost-per-mile may be the attractor, but it's competitive regardless of method of propulsion. I'm sure compared to Dave's family's S550, the Telsa S holds it's own as a car. And clobbers it in efficiency. But was priced similarly, if not less. You can't compare a large sedan that does 0-60 in 3.9 seconds to a Ford Fiesta or Toyota Prius on a cost basis. I'm amazed that you try.
