I was pondering this whilst driving back today. The trip is 472 miles. I was getting about 35 mpg using premium, so about 13.5 gallons of gas at about $4 per (Costco), = $54.
An EV with 300 miles range, well, I'd stop after 280 or so and recharge 100 miles taking about 15 minutes and then again to recharge, if I could find a supercharger of course. Then I'd have the range taking about 30 minutes to recharge. I saw no charger at the motel, maybe there was one around somewhere.
You need about 33 kWhr of electricity for 100 miles range, it costs on average I think 12 cents per, or $4 for 100 miles, if I did this right, or about $20 for the trip. An EV equivalent to my GTI would probably cost $10 K or so more than I paid. We're not there.
