OK, the average mid-grade price over 2000-22 is $2.56/gal => 9.14c/mi (assuming 28mpg comb.), only very little more than 8.25c/mi.
Let's see: Average mid grade price includes the year 2000. That's 22 years ago. There are people working full time right now who were born back that.
Want to get weirder? Back in the late 1950's, when a passenger in my parents cars, I remember gas a $0.149 a gallon. Yeah, 14
cents a gallon. Coming back from camping with the Boy Scouts in the early 1960's? A regular burger at McDonalds, yeah,
that McDonalds, was $0.25.
So, citing gas prices from 2000 is, like, a) stupid, b) disingenuous, and c) just nuts.
Yes: Tesla electrical energy prices
have gone up since I got a Tesla in 2018. So have electricity prices.
Let's see: Fast mid-grade gas prices
right now in Austin, TX: GasBuddy says: $3.43 a gallon. 28 m/gal car gets you $3.43/gal x 1 gal/28 mi = 12 cents per mile. Let's say the SC's on the high side at $0.44/kW-hr. An M3 gets about 250 W-h/mile; so that's $0.44/kW-hr x 0.25 kW-hr/mile = 11 cents.
That would just be about parity, with the Tesla winning. Except the Tesla doesn't need oil changes, water pump changes, and has a heck of a lot fewer mechanical moving parts to go wrong.
And, finally: If one is getting electricity from home: That's typically 1/3 to 1/4 of the cost at an SC. Which is what Tesla says: If you're going on trips, it Superchargers. If you're local, use your local electrical.
