    You are correct. Electric motors are 100% efficient, so a combination of air resistance at speed as well as more regenerative braking being done during city driving are the reasons for better city driving effective mpg.

      Electric motors are 100% efficient

      Umm what? Have you never heard of the laws of thermodynamics? I mean, the overall thrust of your argument is correct, but that statement is just nonsense.

      Oh, and using regenerative brakes will always waste more energy than not using brakes at all and simply moving at a constant speed. Regenerative brakes are only efficient compared to conventional brakes, which waste all of their energy as heat. Braking more in the city driving doesn’t improve an EV’s efficiency there compared to using that same EV on a highway (aside from the fact that you’re driving more slowly overall,) it just improves its relative efficiency compared to ICE vehicles with conventional brakes.
