the ZERO MPG is taken but I also am too OCD for it.

I've put about 1,500 miles on her this month and thus far the Tesla's efficiency equivalence is running 124.69 MPGe. In laymans terms I've been averaging 3.7miles per kwh with no change in the way I drive at all. I can easily get the rated 4.1 but that to me would be boring. Full Self Driving does make that much easier to do though as hands and feet aren't entering the picture.
Just as a cost comparison to my Accord, the cost per mile for fuel there was $0.1385. or $.14 per mile. The equivalent cost for the Tesla per mile is only $0.0551 or $.06 per mile for fuel/energy. Although for me it's going to be nearly free for quite a while as I have 3 months free Supercharging and I also have a $1,000 in referral credits on my account thus that's about 15,000 miles additional free after the 3 months is over.
