National average is about a third of that. For the rest of us an electric car is like driving a car that gets around 100mpg when gas is $4/gallon.
In addition to cheaper power, electric motors are far simpler, more reliable, and easier to maintain. I'm still amazed that internal combustion engines exist. A gas engine has tons of moving parts and they've been slowly improving over the past century. Electric motors were top notch from day 1 because they're so simple. We had electric cars 100 years ago, but they had the same problems as today. The batteries were too expensive, too heavy, too slow to charge, and range is too short.
Batteries are really the only thing holding electric cars back. I'm looking at Tesla website right now, and the cheapest Model S is $66,570. The one with a bigger battery is $73,570.
but they need to bring their prices down before they'll become profitable
They sort of can't. That's really what the car costs. The big batteries on the Model S cost $12,000 to replace. The warranty is for 8 years, so you can expect them to be replaced every 10 years maybe. This really puts a dent in resale value. Imagine seeing a nice car like a BMW 5 series and the dealer says both the engine and the transmission will need a complete overhaul after 10 years and it will cost $12,000 to fix. Would you buy that car? Most people would probably say no, and that's what will kill Tesla.
My prediction is that Tesla will be acquired by a much larger company after their stock crashes. It could be a car company like Toyota, or it could be a company like Exxon. Oil companies are really energy companies. Exxon has put considerable research into battery technology while BP was involved in solar panels for a while. BP gave up on solar after concluding that it's not profitable at this time.
