"In 2009, Elon Musk, the CEO of Tesla Motors wrote, “The ownership cost of Model S, if you were to lease and then account for the much lower cost of electricity versus gasoline at a likely future cost of $4 per gallon, is similar to a gasoline car with a sticker price of about $35,000.” We’re already paying about $4 per gallon today (it varies over time). Gasoline prices are likely to go up, and with that increase in price at the pump, so does the affordability of a Tesla automobile. If the average cost of gasoline is $5 per gallon within the next 5 years, then owning a Tesla Model S, will be comparable to owning a $30,000 gasoline car. But if you’re the type of person that hangs on to your car for 7 or even 10 years, you’ll be saving much more."
El problema es que la gasolina ya esta a $2 y en algunos estados incluso menos.
