Okay. Do link to this post of yours. Don't post any more of your pointless wriggling unless you can provide quoted evidences.
I say it is one thing, someone say the same thing in a different way, I give a like. You just can't read.
Are you sure you did the UK to US mpg conversion correctly?
According to EPA, BMW 330i only gets 30mpg, Ford F150 gets 21mpg.

If you are talking about specifically driving for efficiency. This Model S has gotten 670 miles on one charge.

2017 Model S 100D gets 102 MPGe according to EPA, normal range of 335 miles.

So a big heavy car got 204 MPGe efficiency in 2017. The same battery and car now has improved motor+inverter, 370 miles rated range.
Actually, charging does not degrade the battery. I believe age has a bigger effect on battery capacity. I've seen high mileage and low mileage Leaf have similar battery degradation throughout the years.
For example. "Recently, one company racked up 300,000 miles on their Tesla in just two years, putting their Model X to the ultimate test. After two years of what can only be described as ultimate overutilization, the battery pack of that particular vehicle lost only 12.6% of its original capacity. "
Let's be conservative and say 250 miles range, that's 1200 charge cycles on the cells, only 12.6% degradation.

Yet, over the 300k miles, the electric powertrain did not require as significant powertrain maintenance as ICE.
Whereas a well looked after Skoda Octavia, with 400k+ on the clock, has lost power. Contrary to what you've claimed.
(disclaimer: psudoscience. unfortunately this is needed to combat baseless claims)
