Range factors

[Ampere]

Nobody has mentioned a very important range factor: weight, beyond that of the car. My Honda Accord came without a spare tire. I bought a compact spare for it and mileage decreased by .5 mpg. With the jack it was pretty heavy. One of the reasons Honda does not supply a spare is not only does it save the company $$, but it helps with the EPA mileage rating. When my partner travels with me, mpg decreases. When we load up the car to go on vacation, mpg decreases. The same is true for an EV. Thus, it may not be as easy as it seems to provide accurate range readings on the display.
While this has been mentioned, wind direction and velocity is a huge range factor, even for a car as aerodynamic as a Lucid Air.
