Possibly the EU is pulling ahead on price per mile now with the shift to EVs.
(household elec is about 30-35c/kWh, public charging stations for electric cars often charge 60-70c/kWh, no joke, although I think some vendors now offer 40c charging with a subscription)
If they did all their charging at 70 they'd probably lose on cost to a US car (or a German diesel) but be equal to a German petrol car.
I think Germany has a cultural thing with smart meters which are mandatory for the ultra cheap charging available in many EU countries but it appears that you can get still those rates in Germany and pay about half what you quote, expanding the gap with the average US cost per mile.
I’ve got a Prius Prime and only at around $4+ a gallon does it start to become cheaper to charge than just use gas since the gas engine is so efficient.
This is from a recent PG&E bill from my house:
Peak pricing: 0.48575 delivery + 0.14920 generation = $0.635 kWh
It seems to have gone down a bit this year though. These are the numbers from 2024:
Peak pricing: 0.53 + 0.183 = $0.71 kWh
