MYK-MY: 46k miles, mostly highway, Fort Worth to Tampa, Washington, DC, Aspen, Co...multiple times. The MY computer says my lifetime average is 297Wh/mile. Range anxiety is a myth, once you start trusting the placement of Superchargers, and plan your route accordingly. (Yes, it's a challenge in some regions, off the Interstate grid.)
Range is totally irrelevant, on a road trip, since stopping every 130-180 miles (supercharger distances) is better for my back, bladder, focus, concentration. A 15 minute power nap is exceptionally beneficial. It's safer than thinking you're alert after 180-200 miles, as dozens of tests prove that most people are not.
YMMV, of course, but...uhh...not by much!!!
