Moreover the normal (gas) cars have the same behavior. ... You get the best mpg at a constant speed of ~50mph This isn't true of EVs. The engine in a gasoline powered cars are around 15 to 25 percent efficient, and the hotter you put them, the more efficient they are. However, air resistance increases as speed increases. The peak efficiency depends on a few things, but most cars you'll find it around 40-60 mph. EVs don't have engines, they have motors. They are about 90% efficient, regardless of your speed. But they have the same air resistance issues. So EVs really do perform better at lower speeds. Even the Prius will show better city mileage than highway mileage, and that's only with a little bit of battery+motor.
