This compares gas -> motion with battery -> motions. To close the loop, we’d have to incorporate the generation efficiency. That will still yield an impressive number, but not 5x.

Solar => Car battery you only lose about 10% of energy.

You lose more than that in refining oil to gasoline. And a lot more when factoring in extraction + transportation + point of sale.

Closing the loop makes solar => car even more efficient, not less.

Sure, if we want to be dumb and extract oil to power inefficient turbines to generate electricity this becomes a talking point. But not many people are building new oil power plants for a reason...
