Agree with Adam ; a section to the site should be created highlighting benefits, potential savings for owners.
Sliders with adjusting how many miles you drive, what you currently pay for gas and how much you pay on your utility bill including delivery charges for electricity if they want to really be helpful/educational. Plus of course tout the no gas, no oil, all of the reduced maintenance costs, added time, long warranty on the battery and power train, the expansive supercharger network, etc...
Without a dealer network expecting potential buyers to be educated from outside sources instead of Telsa's own website does not make much sense to me.
To backtrack a little from my prior statement, I do not find it dishonest but
I find the current tactic not well done ; reminds me of the airline industry pricing which is not an industry model I would want to emulate if I were Tesla.
If you were looking to buy a new furnace or air conditioner you would want to know your actual cost not some hypothetical cost based on efficiency savings that I may or may not experience.
