Agreed with most of your points, just curious about:
> Same way you won't get good mileage on any car if you do that
What do you mean by that? Aren't ICE cars often more efficient at highway speeds? My car usually averages 45ish MPG on the highway and more like 30 in the city.. the sweet spot seems to be around 60-70 mph. Some US highways get up to 80 or 90, but that still (at least for the cars I've owned) ends up more efficient MPG-wise than city driving.
The sweet spot for your car is actually more like 45-50 mph, but you are not really going to find long stretches of road with those speeds.
Try driving US highway 1 from Key Largo to Key West. It’s about 100 miles with a 45mph speed limit, at sea level. Set your cruise control at 45 on an evening with light traffic. It will be the best fuel economy you’ve ever seen in your car, by a wide margin.
> Aren't ICE cars often more efficient at highway speeds?
No. They're more efficient at constant speeds, because the ICE can only be really optimised for a very narrow RPM band, but that need not necessarily translate into higher speeds.
Just choose a lower gear, and watch your fuel consumption drop significantly below what it would be at higher speed in a higher gear.
The main reason for this is that air resistance, which costs energy (=fuel) to overcome, rises not linearly with rising speed, but in proportion to the square thereof.
