The actual savings of electric vs gas, is not as great has the Tesla calculator claims. The calculator factors premium fuel costs at California fuel prices, but then calculates electricity costs at U.S. average of .11 cents per KWH, while California rates are .227 per KWH. Plus the calculator, uses premium fuel costs, not regular. When you change these 2 factors, the actual saving drops to $140 per month from $255, based on 15,000 miles. The Tesla pricing calculator, borders on deception, and is not something I'd expect from this company. The advertising team at Tesla, would like everyone to believe, driving a Tesla, is almost free, no fuel costs, no CO2 pollution (what about that power plant producing the electricity, or is it a Nuke?) Borders on deception, no, it is deception. I was almost finished with the order and deposit, when I studied the calculator, and then decided to wait. Then I read other comments about the tires wearing out at 10,000 miles. Most cars will get at least 35,000. I checked the prices for those 21in. tires, how about $2800 for 4, installed and balanced. I thought my 911 tires were expensive, these are double. I'll wait or look at a hybrid, at least I won't have to buy a $2800 set of tires, every 9 months.
