Maintenance and repair costs of a gasoline vehicle over 10 years can be less than that.
Electric cars also have highly sophisticated power control equipment. In 10 years of sysadmin work, the overwhelmingly most common failures I've seen have been power supplies, voltage regulators, and capacitors. Remains to be seen how well these components will hold up in real-world use in electric cars.
I wouldn't be at all surprised if batteries for a car like the Tesla got down to $6000. At that point, the value proposition is already much better than gasoline cars.
I think just brake pads, tires, and regular maintenance exceeds $600 a year if you amortize it. Every older car I've owned then started having problems. Even if it's just the A/C compressor or the muffler, you are always replacing something every few months.
If they can get battery costs down, which they're doing at a speed of 10% a year IIRC, then they can decrease that figure to about $200/year a decade from now.
Come to think of it, perhaps in a decade we'll finally have a reliable carbon price, rather than it being an unpenalized externality. That'd make ICE cars fairly uncompetitive quickly.
