Assuming 7 pounds / gallon and 30mpg, a gas car would cost 23p per mile. Assuming 28.2p/kwh and 300wh/mi that comes out to about 8.5p/mi (figures pulled from Google for London, no idea if they're accurate, I'm in the US). In my experience that 300wh/mi is generous (my 2022 model y is usually closer to 350wh/mi in the summer driving downhill with the wind at my back and up to 450wh/mi in the winter). In any case, it doesn't seem to be anywhere near 1:10.

Do you drive like a maniac? Even here in Texas where you need to run the a/c full bore most tesla drivers see 250-300wh/mi.

No, and I'm actually worried that I got a shit battery. It also charges at max 60kw. I just drove from Illinois to Denver and we got an average of ~350wh/mi (we had the A/C on but we tried to moderate it to save battery).

There are charging losses to take into account as well. I think my gross is closer to 300 wh/mi lifetime than the 260 or so that the car reports.

My figures were not gross, sadly. :(

Energy pricing doesn't have to be constant - there's tariffs available which have cheap overnight electricity (eg Octopus Energy) - if you sign up now it's something like 7.5p/kWh, but some older contracts have it at 5p/kWh. You pay more during the day, but if you're charging a car a lot then it works out cheaper overall.
