Using the configurator model under any Tesla vehicle, the price detail page proudly shows "estimated 3-year gas savings" upwards of $3,900. We should all be in agreement that yes, you won't ever need to buy gasoline for driving your Tesla. But the obvious question is, you're paying at the Supercharger, you're paying to plug in at home. Depending on your area, electric rates and Supercharger stations are charging a premium rate. So, the obvious question is: does the estimated 3-year gas savings take into account the difference between what you would pay for gasoline vs. electrical rates at your home and the SC station? Hasn't this claim been challenged by TMC, consumer groups, etc. or is this the first post on this topic? Thanks for your replies.
