RE: Tesla's Model S will go 300 miles and cost $77,400
This model of Tesla is an improvement, no doubt, but still not
economical. First, electricity is not free, and there would be a charge no matter where you go. Asking your friend if you could plug in to his electric plug is the same as asking him to siphon from his tank into yours if both were gas. And companies are not going to offer plugs for free. So we have to determine what a '300-mile' electric charge would cost in real dollars. Probably $5 - $10. That gets a person 300 miles and then they must 'refill the tank" - recharge. Assume once per week is an average fill-up. Now you can compare costs of either option - gas car or electric car. Assme a 300 mile range on the car for gas, and done once a week, and now you can begin to compare. Put the average price of a new gas car at what the average public buyer can afford - say $25,000. With gas at $3.25/gallon and the car gets 25 mpg, it takes 12 gal, or $39 to go 300 miles. Work out the simple math and the $77,000 Tesla will begin saving you money after 34.5 years! Now, guess what happens? The Government takes very little action to stabilize the price of gas, like opening oil drilling and new fields that the US already owns, and gas goes to $5, $6, even $7 gallon, and the Tesla starts looking better, doesn't it?
Things that make you go "Hmmmmmmnnnn!"
