In the case of a full EV like a Model S, you're also paying for all the fluids, belts, parts changes, spark plugs, oil, oil filters, starters, alternators, clutches, hoses, wires, brakes (if you know what you're doing), rotors, 12V batteries, mufflers, catalytic converters, etc. and all the associated labor. People don't actually get how expensive it is to actually maintain a gas vehicle, especially as it ages.
Also, in the case of the model S, it is priced in the same range as the cars it competes with. People spending that much on a car are already not very concerned about the price.
