The realization that the MY typically never comes close to its rated range came as a shocker to me. During the summer my consumption was over 340 Wh/mi. Now with cooler temps (but not freezing), I'm doing about right about my overall average of 260ish Wh/mi. And yes, speed does make a HUGE difference in consumption. On our recent trip down to SoCal over Thanksgiving my wife was driving 85-90 mph. Consumption was abysmal. I drove about 75-80 mph and it was still terrible. One thing I noticed is the Tesla nav will tell you where your next scheduled Supercharger will be. But I almost always end up having to charge up before I reach that originally planned SC. I had planned my route on ABRP, and NONE of the stations I had scheduled after entering in starting SOC, speed, etc., came to be. I always used way more electricity and had to stop for charging sooner than planned.
All that being stated, it really didn't make that big of a difference for us on that trip, since we were going down California I-5 and there are lots of SCs along the way. It would be a real PITA and a big concern if I were on some lonely highway and there weren't many chargers along the way.
